Using of Pressurized Co2 in a small tank.

[Naraki]

Hi guys, I would like to ask if any of you is using pressurized Co2 for nano tanks like 25cmx30cm and below.

Or if is it advisable to purchase a set for a 25x30?

I am using Aquazonic LED 27CM. 15.72w ( Three 10k, Four 8k, Three "x" LED)

I have-Hydrocotyle verticillata 5%
Mini Fissidens 5%
Japanese HG 3%
Alternanthera reineckii 'Mini' 75%
HC 2%
Anubias Nana 10%
3 Stalks of unknown plant. Seems like narrow sword.

Root monster in substrate and Excel 1ml every 2 days or 3.


Thank you!

And the concern is?

And the concern is?

Concern is, Does it overkill even if using 1bps. Or it is not neccesary or wasting resources because the time from being release into the water to the water surface is under a second

Investing into a reusable CO2 system is never a waste of financial resources depending on how you want to look at it from a broader perspective.

The answer to your question lays here:

1. Are you going to be in this hobby in the long run?

If the answer is no or not sure, then I suggest that you give it a careful thought. As all this equipment as I have mentioned is an investment. It is worth next to nothing if you decide to give up the hobby. If your answer is yes then....

2. Do you have place to hide the bloody CO2 tank?

Unless you are prepare to pay the price of an ADA CO2 canister and regulator that makes any aquarist salivate,then hiding a relatively ugly canister can be an issue.

If you do have a cabinet or a place to hide it, and you are going to be in this for the long haul, get it. It's worth the investment. You using excel is not cheap over time.

PS: I will see your tank tomorrow as Malaysia 3G SUCKS and tapatalk is a really pain to use.

Its rather funny thou. I've a 4ft, then a 2ft. Now a 25x30 . haha
Yes, I'm into this hobby from long ago.
Canister can be hidden. No problem.
Im looking at a 3l aluminium cylinder. Which i believe can last me above 1year using at 1bps on a 8 hour basis.

With the right regulator and diffuser/reactor combination suitable for your tank, a huge honking CO2 tank can be used for your nano tank too, the only real problem is where you're gonna put it and how you're gonna refill it of course...

Co2 injection is still useful for small tanks, it'll benefit the plant growth, but you'll need to monitor the Co2 levels in the tank more carefully as any fluctuations will be quicker than in a larger tank.

Just looking at bps isn't a reliable gauge on Co2 concentration in the water... the actual amount of Co2 that gets into the water depends on the tank volume and how well the Co2 is diffused and circulated around the tank. It'll be best to get a drop checker to monitor the Co2 levels, or else it'll just be alot of guesswork.

Case in point, i was using an in-tank glass diffuser and i found that i had to do 3-4bps just to get the drop checker green, even with output flow directed against it, i still noticed most of the bubbles were just floating up and swirling around at the water surface... then i installed an inline diffuser which made bubbles even tinier so they didn't float and i could see them suspended in the water and evenly distributed around the tank, even at substrate level can see the tiny bubbles settling around the plants. Now i only need to do 1 bps to maintain my drop checker green, so i attribute it mainly to the more efficient diffusion rate and better circulation of the Co2.

No problem with placing the cylinder.

I was using a Dymax glass diffuser too on a DIY setup. I too notice the bubbles were too big. Guess I should invest in a in line diffuser. Hmmm.

Thanks guys for the input.

Anyway. Anyone can identify the plant besides the verticillata? The long narrow leafy stem plant.

For immediate same day CO2 top up I know system and control does it

Sorry to OT abit, does your dymax glass diffuser work on DIY setup? I got one from ANS, however, could not get any bubbles out, able to work on airstone though.

If you're going for a CO2 set, i would recommen you going for one with a solenoid.

if you;re talking about difussing and not enough height for the tank, you can consider inline diffusers, or those reactors that ensure almost 99% dissolvability rate.

depending on the requirement of your tank, you might not even need 1bps, will be good if you have a drop checker to gauge to right amount of co2 youre injecting.

Yes it does. Your DIY setup had leaks if you are not getting any bubbles from the glass diffuser, Because the pressure is not there to push out the bubbles, While air stones require minimum pressure..First time i used a bottle bubble counter after few trial and error with silicon, I found out that, that bottle had leaks(The pressure is not there and it backdraws<Indication of leaking.). So i thought, forget it just get a commercial bubble counter, Not very expensive. Only $6, Also from dymax. Works great.

Going for electric solenoid. And shall search around for small inline diffusers.

You are going the wrong way, its suppose to be 25x30 then 2ft then 4ft then 6ft then 8ft and Olympic size pool...

For inline diffusers you will need a higher working pressure due to the pressure of the water inside the inline, as well as pushing them through the fine ceramic plates.

You can take a look at up brands inline Atomizer, but will need a working pressure of well over 40PSI for it to work properly..

[milk_vanilla]

Buy UP1st generation atomizer, even my ans solenoid strong enough to burst co2 into mist

Order from ebay.

Haha @ Zero...his way means his aquatic skill is proving ...the smaller the tank more skill is needed.

Like Assassins...from sniper kill shots to up and personal knife kills...

smaller tanks are definitely much harder to scape..
