Firstly, I only know yeast type CO2 working on very small diffusers? How big is the one you have?

As to the question don't worry about the water in the tubing, it should clear of its own accord. And it shouldn't break the disk as when it gets into the diffuser the gas just passes over the top. Ive had my diffuser almost full with water and it still worked fine

As to placement, put if in front of the filter outlet that way the CO2 gets blow around the tank.

My ADA diffuser gets water in it also. It is not a problem the gas just bubbles through it. However, it does not clear completely from the unit, to clear it you need to tip it upside down when the gas pressure has got high enough, this clears it and keeps it clear. I think the problem you will have is the pressure is not high enough and the water will leak back in (since when the water goes out the pressure needs to build up higher since there is an decrease in pressure due to the volume of gas and liquid, you will see what i mean when you try it) To overcome this, i suggest turning it upside down, letting the water drain out, LEAVE it upside down and wait for the pressure to build back up again and bubble through. Then flip it the right way up and the pressure will be high enough to stop the water coming back in. lol, you’ll see what i mean when you have a go. BUT to be honest, it doesn’t matter if it has water in it, it just bubbles through, it just doesn’t look as neat.

Let me know, i still have reservations whether the yeast DIY system will produce enough pressure to expel the gas uniformly around the ceramic disk.

Good luck.

Regarding placement, it depends, you can try the CO2 mist and have it directly opposite your filter outlet, thus causing the bubbles of CO2 to be blown around your tank. Other than that you can shove it anywhere, as long as its bubbling CO2 will be dissolving. However, since you can not control the rate, you can not determine the CO2 concentration.

I have this attached to a 2ltr DIY CO2 system and no problems with it so far.

I got some water it there at one point but it didnt cause any problems.

The CO2 does not seem to bubble from the whole surface of the ceramic disk, I suppose it must be from about 60%, but as the CO2 levels in the tank are at about 30ppm I'm not too worried.

The only thing I found was I had to include a smaller (300ml) bottle into the setup to cut down on the amount of 'muck' (CO2 snot! )that was collecting on the surface of the ceramic.

When I came to placement, I was a bit stuck. The tank it is in is only very shallow, so some bubbles do reach the surface, however as mentioned my CO2 levels are OK for now so it's not a problem

It's not ADA, I got this from an Ebay seller in Singapore -> Aqualogy Aquarium Supplies

The price was pretty good, but I ordered a few items ( tweesers, scissors, plants) to get the better deal on the postage. All arrived in good condition and got good communicatons from them.

I'm thinking about ordering their "Gamba XII Japanese bubble counter" to go with my pressurised system, once I get the tank setup.

Who knows! Guess you'll find out soon enough!

That diffuser is rated for 100G tanks! thats a hell of a tank!

Why don`t you double up on your yeast and sugar. That way you will get twice as much CO2 produced and thus pressure, however it may run out quicker.

On the other hand, the glass diffuser on my 4 gallon nano still hasn't produced any bubbles. The bottle is an 8 ounce soda pop bottle (smaaaller than the 2 ltr I used for the 10 gallon). Would it produce enough pressure for the Co2 to push through?

I know this seems like an obvious question, but I assume you've double checked the seal on the 8oz bottle ?

One thing I noticed with a pop bottle and my glass/ceramic diffuser is that the pressure in the bottle is much higher that when using an airstone or nutrafin ladder, for obvious reasons. (If i just gently squeezed the bottle it is rock hard)

Obviously there needs to be be a higher pressure to force the gas throught the ceramic and even a slight imperfection in the seal would allow gas to escape.

One thing I've found is that if I push a lump of blu-tack inside the cap of the bottle and then screw it on tight it really helps with achieving a gas tight seal !

I gave the soda bottle a squeeze, it's pretty darn soft. There's a leak doh!!! I'll see if we have blue tack stashed somewhere. Thanks for the tip!

My bottle was so hard, I even put it in a bucket with an old towel over it ...... I was half convinced it was going to live up to it's description as a ''POP'' bottle !

But in the end it just started bubbling !
