i think this can work we can make it a triangular composition sort of like this way

and actually in the cabinet i've set up a little plant holding system okay

so while the tank is filling up we can have a look at this new filter

okay plan for today is to set up this tank right

here this used to be the low tech slash low budget aquarium for my 2025 aquascaping beginners guide

if you have not seen

that guide you want to watch it i'll leave a link

in the video description it's a seven episode series covering everything from start to finish about aquascaping

so we basically have two identical setups the only difference is

that this tank is made from regular float glass

and this thing is made from optic white glass so

that glass is a little bit higher quality a little bit

more transparent this one has a bit of a greenish tint

to it i did upgrade the light on this tank

so we now have two of the same lights

and these are twin star e-series 4 i just think they look really nice with the acrylic legs you know

so i've upgraded the light on the setup

and i'm actually also going to upgrade the filtration

because i used to run a internal filter from superfish i think it's quite bulky

and just doesn't look very nice

so i'm going to upgrade it with an external cancer filter

this is the new eheim classic vario it's not sponsored i

bought someone with my own money i actually saw this filter

for the first time at interzoo last year spoke to the guys from eheim

and i was quite curious to test it out

so i saw it on sale recently

so i thought let me just try it out of course

i'm not going to install the filter now although the ones escape is completely done

but i'm excited about this product so uh yeah something to look forward to

so this layout i made a few days ago

and this is going to be a real classic nature style

escape you know like carpet in the foreground crypts around the wood ferns on the wood

and then colorful stems in the background

so of course this one should be something a little bit

different i'm thinking of making sort of like a river star escape

but actually a heavily planted river if that makes sense

so i have these really nice dark gray boulders

and long-term viewers of the channel might recognize these stones

because last time i used them was in the 90b river

i think this layer is going to be quite similar i was thinking of doing something completely different

but i really enjoyed the layout you guys enjoyed it as

well i think the video got like more than 100 000 views

so yeah i want to just try something similar again

but first things first we need to take care of this substrate

so So this is the old substrate on the previous layout.

I definitely want to reuse it again because it's full of beneficial bacteria.

It's only six months old, so there's probably still nutrients in there as well.

But I do want a cosmetic sand foreground.

So I'm going to push some substrate towards the back

and then kind of clean it up a little bit here and then add in some sand and some gravel.

I want to try to siphon out this last bit of water because it's quite dirty.

So I'm going to raise one side of the aquarium.

okay remove the aquasol from the foreground i don't think it's a good idea to add in the sand

and gravel now because i'm going to be using quite heavy rocks

but the aquasol is still going to be shifting around

and moving around so it's probably going to be to save that till the very last so

yeah let's get some of these rocks in so i've used these rocks a few times now and

every time I've used them I've glued the hardscan together.

So these rocks actually have some glue marks.

I don't know if you guys can see that.

Yeah you can see there's a lot of glue marks on there.

Unfortunately there's not really much I can do about it anymore.

It's very difficult to remove so I'm just gonna have to find a way to make sure it's not visible.

So either you know face this rock the other way

or cover it up with some plants or something but we'll figure something out.

I think the other side doesn't really have much glue marks.

so this one could stand like this

wasn't really happy how things were going so we're starting from scratch again

and this time this time i'm going to start with the wood

because the wood has quite a nice flow i think i want to have it like

that so now i'm going to start adding in the ropes again

so i do want this piece of wood to sit a

little bit higher i think this can work we can make

it a triangular composition sort of like this way i have

a much more density plant on this side taller plants as well

and then just have it sloping down towards the right i

think this could be nice i do still have quite a lot of these smaller pebbles

but at the moment the piece of wood is touching the glass over here

so i'm just going to move it forward slightly

i think i think this is good now i can also have plants over here you know otherwise

would be hard to kind of cover this up

so initially i was thinking just have a line of sand

because metal gravel in the foreground but i'm thinking to have soil until there

and until there and then just have sand in the middle

and have it going up up on the hill as well you know i think

that could be nice so i'm going to add a little bit of new aquasole in each corner

just to raise it up a little bit here we go

so now this side and this side can also be planted

This will remain empty and later on once we're completely done we'll add in some nice cosmetic sand.

Right I quite like where this hardscab is going.

I can kind of already visualize how it's going to look with the plants in there and the sand in there.

Next step is to glue this piece of wood to the rocks.

I just wanna have it secure, you know?

So I'm just gonna use my super glue and cotton pad method.

A few spots here and there just to hold it down.

okay i think piece of wood is secure yeah it's not moving anymore

so we're pretty much ready for planting but before we do

that i just want to add some root caps into the

substrate like i said it's been six months this actual six months old

100

so i just want to make sure we have enough nutrients for another six months

101

so a couple of these dental plants power caps in there then we should be good

102

you want to push these in quite deep because those capsules always have a little bit of air in it

103

sometimes they want to float up to the surface

104

i'm going to put three in the background here

105

and then a few more over here okay root taps are in

106

so now we can start planting

107

so i'm thinking for the left back corner to use the nymphoidus telman this will look really good in there

108

and then i'm also going to add in some of this juncus repens is a nice grassy stem plant

109

so just mix

110

that with the nymphoidus taiwan then i have some taxophyllum barbeer

111

also known as java moss of course it's going to go on the wood

112

and kind of like in between the smaller rocks

113

and then for these shorter areas over here i'll use the halantium broadleaf

114

and halantium red and actually in the cabinet i've set up a little plant holding system

115

and in here i have a few more options i have

116

some really nice hydrocotilde verticillata in here i do have some

117

small amazon swords as well got some hair grass i got some pearlweed

118

some sagittaria as well so i might pick a few of these as well

119

all right all done planting i like it a lot already i think it has a very natural feel to it

120

so the only thing i have to do now is to add in the sand

121

and the gravel i think in order to do

122

that i'm actually going to fill up the tank with water first then siphon out this little bit of mud

123

that we have over here in front maybe siphon out a little bit of excess soil on the path

124

and then I can add in the sand and the gravel.

125

Okay, so while the tank is filling up, we can have a look at this new filter.

126

We've got a huge thick manual and we also have a quick guide.

127

So I'll probably just read the quick guide and get rid of the manual.

128

And here's the filter itself.

129

Even though I have seen this thing about a year ago, I'm still quite surprised how big it is actually.

130

and it's not that powerful i think this wind does like 510 liters per hour

131

which you know it's not actually not

132

that much yeah at least there's a lot of space for uh for media

133

and stuff like

134

that let's see what kind of media is in there actually

135

yeah i'm not going to open it up as you can see it's basically just sponges

136

but that's not biological filter media it's kind of weird as

137

well you know like it's it's not a cheap filter why would you only put sponges in there

138

and besides the filter of course you get a bunch of tubing you get four of these valves

139

which is nice of course all the pipe work for the in

140

and out flow which i'm not going to be using

141

and then of course the uh the power brick

142

and the electricity cord okay back to the tank so i'm just going to start siphoning

143

i just want to remove this little bit of mud over here and a little bit of soil

144

in this area over here.

145

So I've just been digging through my collection of sands and gravel.

146

I have this Dua River sand, tropical river sand.

147

It's quite nice.

148

I have the classic ADA La Plata sand.

149

And then I also have this gravel from WIO, which I also used in the previous River Lail with these rocks, you know.

150

Here we go, this is very similar to the boulders that I've used for the hardscape, you know.

151

So I think a combination of these three materials should look very nice.

152

Okay, all done with the sand and gravel

153

but of course it's super cloudy because MJ didn't bother to wash anything

154

so I'm just going to quickly install the filter

155

and then the filter will clear everything up

156

so I think I'm going to have to say goodbye to my plant haunting station

157

because I need the space for the external filter

158

so instead of the standard filter tubing i'm just going to use this

159

flexible filter hose from chihiros pretty much use this on all my tanks now

160

so this is what comes standard with the eheim filter not necessarily bad it is quite flexible

161

but it's also like kind of a dark brownish gray color

162

not very pretty i think this looks a lot better i don't know

163

if you guys can see but i also have to go through this little gap over here

164

there's a hole in the cabinet

165

and then i have to go out to behind the tank

166

so this is really flexible hose from gyros it's great for

167

that it's not sponsored just a product

168

that i like instead of using the standard in and outflow

169

which is also not a very nice looking color i'm going

170

to upgrade it to the aquario neo flow they're actually the same shape

171

but this one is transparent and this one is not wondering

172

if it's made in the same factory i don't think

173

so probably not okay filter is installed

174

and the in outflow is installed as well now this filter doesn't even have a prime function

175

so we're gonna have to do it the old-fashioned way

176

and in case you're wondering what the old-fashioned way is it's basically removing the tube making sure

177

that the inflow is fully submerged and there we go now it's priming

178

okay now the filter is slowly filling itself with water okay it's all filled up

179

so now we can plug it in

180

and we have flow seems quite powerful actually okay i finally

181

managed to connect the filter to the iaheim app i'm now

182

running it on 50% of issues oh i think it's good i'm now going to add some ada clear water

183

and hopefully in an hour i think it's crystal clear

184

okay fast forward to the next day tank is looking good water is crystal clear

185

and i'm quite happy with how the senpa turned out i

186

think it's looking really good only thing i have to do

187

now is to add in the co2 didn't really have time for it yesterday

188

so i'm gonna do

189

that now okay plenty of space in cabinet for a co2

190

system i have a brand new 500 grams co2 cylinder remove the packaging

191

because it's new it always has this yellow seal on the uh the output so i'll just remove that

192

and now we're basically ready to go full of co2 these 500 grams co2 cylinders they can't really stand alone

193

so they need to have a foot as well

194

so we're just going to put it in the cabinet like this then next up we need a co2 regulator

195

and i'm actually going to use the two heroes co2 regulator

196

mate i think it's called i've shown this one once before in my 2024 co2 system buying guide

197

and since then i haven't really used it

198

so yeah it's perfect for this small system okay

199

so the regulator is attached to the cylinder now i just

200

need to fill up the bubble counter you can do this

201

with water i actually like to use glycerin you can find this in like pharmacy and stuff like that

202

not sure what it's normally used for

203

but this stuff is a lot thicker than water

204

so it also doesn't evaporate so

205

if you fill this one with water over time the water will evaporate

206

or will just end up in the tubing

207

and you can't really count the bubbles anymore you know with this it's a bit more of a permanent solution

208

Then for the CO2 diffuser I'm going to use the NEO diffuser from Acario.

209

This is the special curved S.

210

So I think this is not the smallest one but the one up basically.

211

They have tiny S, M and L I think.

212

There it is.

213

Really nice diffuser.

214

Really good size as well.

215

I like that it has this curve here, so you can just hang it over the glass edge.

216

You don't need any suction cups.

217

Next up, I'm gonna make a cut in the tubing somewhere in the middle and add a check valve.

218

Focus on that.

219

There's probably already a check valve in the CO2 bubble counter, but I just wanna prevent having the entire CO2 tubing being

220

filled with water after the CO2 turns off you know

221

so just gonna have a check valve locked close to the diffuser to prevent

222

that here we go so diffuser tubing check valve is over there

223

and I'm just gonna pull the tubing so the check valve is not visible

224

here we go

225

so we're all done setting up the CO2 system we've got

226

micro bulb was coming from the diffuser only thing you have

227

to do now is to add a drop checker to the

228

aquarium i think i'm just going to place it in the back corner over here

229

so the drop checker is just going to tell us how much you do we have in the aquarium

230

so blue is not enough over here in this one it's yellow it's bit too much

231

but we don't have fish in here just yet

232

so that's okay this one has been dialed in a long time ago it's a nice lime green color

233

which is perfect you really want to dial it in as soon as possible

234

because once you start making adjustments like a week in

235

or two weeks in the chances of getting some algae issues because of the fluctuations is a little higher

236

okay guys roughly five or six weeks have passed

237

and this thing developed really beautifully

238

and really fast as well i mean it's not totally surprising

239

we use like quite a lot of fast growing plants we use the pearlweed the halantim in the foreground

240

so this one grew in fast also had absolutely no startup issues whatsoever like no brown algae no diatoms nothing

241

and i think that's because i really used the substrate on a previous layout you know like

242

that stuff is full beneficial bacteria you kind of instantly cycle

243

the tank you can also kind of skip past the ugly face doesn't always happen

244

but in this case it did

245

because some really nice inhabitants in this tank i've added a mix of celestial prodenius

246

and the emerald resboras so the celestial prodenius have a blue body with dots

247

and then red fins and the emerald resboras have a blue body

248

but with like vertical stripes i think they're the same family sort of

249

and i think they can actually breed together as well

250

but um i don't think that's going to happen in this tank

251

and even if they would like the the babies probably wouldn't survive there's too many predators

252

and i've also added the borneo loaches really love those guys

253

because they stay quite small

254

so they're the perfect size for this nano tank in my opinion

255

and some of them have really beautiful blue tail so

256

they're really interesting fish to watch they really can keep the the rocks nice

257

and clean there's a bit of green algae on the rocks

258

but yeah that's food for them so i kind of want

259

that so that's all the fish

260

and then we have some shrimp in here as well we have a nice group of crystal red shrimp

261

and there's some amount of shrimp in here as well i

262

really love the crystal rats like they're probably my favorite i

263

would say yeah i think crystal that's my favorite shrimp a

264

little bit more difficult to keep you know a little bit more finicky when it comes to the water parameters

265

but um they seem to be happy in here so

266

if they're happy i'm happy as well

267

so i think that's all the inhabitants i mean there's a few snails in here as well

268

but yeah i think i've mentioned all of them

269

but you might have noticed that some of the plants have changed a bit

270

so initially i planted the nymphoilus taiwan in the background

271

but unfortunately almost all of it has melted

272

so instead i planted the um hydroclase nymphoilus if i pronounce

273

that correctly it's like a little south american water lily

274

and uh yeah kind of a similar looking plant

275

but a bit different and then i also wanted a little bit more color in the layout

276

so i added a few stems of the prosopinaca no there's

277

no point right persicaria that's it few stems of persicaria

278

and there's a few stems of red miriam film as well just for a little bit more color oh

279

and of course the the redwood floaters i did also add

280

a light screen to the aquarium i'll turn it on right now

281

so this is without the light screen

282

and this is with the light screen you guys let me know what you prefer i sometimes turn it on

283

but for the most part i just keep it off

284

but it's it's kind of nice when you're making some cinematic footage you know

285

in terms of maintaining this tank it's kind of the same

286

recipe as always light is on for eight hours per day

287

from 1 pm to 9 pm it's not on the full brightness it's the one step lower

288

and co2 starts two hours before the lights turns off one hour earlier

289

and currently in terms of fertilizer i am dosing the ccam flourish this is kind of an all-in-one fertilizer

290

but it doesn't really have a whole lot of nitrate

291

and phosphate the nitrogen phosphate is mostly coming from the fish waste

292

and from the food

293

so yeah this is uh this is working well right now i really love seeing all the fish

294

and the shrimp kind of yeah just hanging out underneath the arch sometimes they do come out

295

but um yeah really happy with this layout hope you guys

296

enjoyed this one as well um i think this is it guys thanks for watching see you in the next one

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
