Awesome thank you!!! I was interested in putting a bubble maker in my betta tank? Not a good idea? I know they like calm water..would that make it have too muc flow and stress the betta outBDpups said:I wouldn't worry about CO2 myself. In that small of tank if you do a DIY set up it can cause PH swings which aren't good for the fish and can grow algae. And if you go pressurized, the equipment for that will run between $100 to $150 for a reasonable
set up. It can get much more pricey if you go for the high end stuff.
If anything you can dose Seachem
Excel. A carbon source that gives similar results as CO2.
