Anyone have homemade CO2?

  • We are currently upgrading MFK. thanks! -neo
ShadowVengance,

Sorry I was intending to reply to your questions.

I am using 2 2L pop bottles in my 48 gallon tank without any problems. A batch will usually last 15-20 days, so what I do is stagger the changes so that I am refilling one bottle every 10 days or so.

Sorry I can't look at your picture yet... not enough posts! :cry:
 
now, if we could just use this system to make beer at the same time....

the airline going from the soda pop bottle can that just connect to an airstone that sits at the bottom of the aquarium?

I believe that you can use an air stone. However I have a couple of concerns about it, I don't know if they are valid or not.

1st.. How much pressure is needed to expel the CO2 from the airstone? Perhaps the pressure needed might be a bit more than you would like in a DIY system.

2nd... How much CO2 will get into the water? I use the Hagen ladders with my DIY setup and the bubbles are pretty small by the time they get to the top of the ladder.

Anybody have an answer to these questions?

airstone nope not enough pressure i've tryed many variations no go bubbles too big i use bubble counters cheap and effective or if you can stand the noise put the airlin directly in the intake of your filter and let the pump do the work be warned the noise will drive ya nuts FNH.....
 
You could, but I don't know how much good it would do you. The idea is to get the CO2 to dissapate into the water. Wwith just the tube under a rock all you would get is a large bubble going straight to the top of the tank. Very little CO2 would actually get into the water.

You really need a CO2 ladder of some type.
 
The tank I plan on putting this on is a 40 breeder, it has a penguin 330 filter, would it work if i drilled a hole in to the side of the intake and put the airline tubing into that?
