Wat abt check valve? Do you need one? How do you prevent the mixture from getting into the tank? I heard it can be quite messy if it flows into it. Does placing of the CO2 bottle important? Would it be better to have it below, above or next to the tank? Does the tube goes under the mixture or at the 1/4 airspace (between the mixture surface and the cap) of the bottle?
Sorry for such innocent questions but I'm new to this.

How to pipe the co2 to the inlet? Just place the co2 outlet below the inlet of the filter and let the suction suck the co2 bubbles into the filter?----------------

you can pipe the co2 to the inlet of your filter.
the impeller blades will breakup the co2 bubble.

It's good to have a checkvalve. But I do not have it and don't really require one. What I did is to have a slightly longer tube to the bottle. IMO, there isn't much or rather dun have any water to flow back to the bottle.
And yes, very important, have the bottle by the side or on top... but definitely not below as it can result in siphoning. That will be disaster! As for the tube, get it as near to the top as possible, try avoiding the mixture in the bottle.

the inlet pipe have the grille to prevent fishes sucked into the filter right?----------------

reduce the diameter of the pipe by using a heat shrink tubing and a small diameter tube.
stick this small diameter tube into the grille.

When you say disaster, what exactly would happen if the water were to get into the bottle, or vice versa?
Is bubble count important and will the tank be overdosed if the CO2 supply is not controlled? Any effect on the fishes? I have rummy nose, cardinal tetra, oto and puffer fish. I'm not sure the name of the plants but I have a good mixture on the fore, mid and background.
Your kind comment pls.

I have finally settled to DIY rather than spend on a ready-made JBL CO2.
Got a 900ml bottle. My mixture is 2 cups of sugar, 1/2 teaspoon of baking soda and yeast each. Waited about 4 hours before the first bubble appeared. Now the rate is one bubble per 2 seconds. I also got a 2-in-1 reactor/diffuser attach to the filter outlet. I used the container type bubble counter as a 2-in-1 check valve cum counter.
Hopefully all these efforts pay off to keep the plants alive.

can i know how you guys prepare the yeast?
btw,
after everything done, how to fix the tube?
i'm trying to do a DIY CO2 also, but very blur about it.
do you mean fixing the tube to the cap?----------------

you can get a plastic airstone and use the air line attachment.
then drill a hole slightly smaller than the diameter of the air line attachment.
fit it into the cap.
use super glue or hot melt to seal.

If you are using an external filter, get a CO2 reactor ( those green ones with bioballs inside ) and connect the tube into the reactor to mix up the CO2 properly. I just allow the water to flow freely from the reactor into the glass of the tank without connecting back the rainbar to it...----------------

Anyone has good suggestion whether a reactor or diffuser is better for a DIY CO2? If I'm using an external cannister with spray bar outlet an inch beneath the water surface, would it undermine the performance of the reactor?
How much is each type and do you recommend a check valve and bubble counter to go with it?
I'll DIY the CO2 soon and guess I need one or more of these items to set up right?
----------------
Yes... pls also use a bubble counter to see how much CO2 is releasing and also to prevent thyeast solution from going into your reactor.
After around 2 weeks + when the CO2 start to diminish, I just add more yeast and baking soda to make it last another week or so.... I try not to waste the sugar...
Always add as little yeast as possible, b'cos if you add too much yeast, the CO2 will finish very quickly... since you will be using a reactor, the CO2 will not be wasted as compared to an airstone..
Hope this helps to clear things up a little..
Its been a week with the DIY CO2. My 16 variety of plants in my tank are doing very well. Have the CO2 for 24 hours and buble count is 1 per 2 sec.
One question? When do I leave the lights on? I set the timer to turn on once in the morning (3 hrs) and once in the evening (4 hrs). No lights in between.
Am I doing it right?

can anyone tell me where to get baking soda?
i would also like to know how to prepare yeast?
pls help me!
ntuc, in the baking supplies section----------------

you'll find both baking soad and dry yeast (in packets or bottles)
