kevin222 Posted August 30 Share Posted August 30 (edited) For a 5-gallon betta tank, a sponge filter with an air stone is a good combo. Just keep CO2 levels low (5-10 ppm) and water flow gentle to avoid stressing your betta. Edited August 30 by kevin222 2 Link to comment Share on other sites More sharing options...
Dacotua Posted August 30 Share Posted August 30 I would not put CO2 in a 5 gallon tank. Your sponge filter would be fine. 1 Link to comment Share on other sites More sharing options...

Jayden Gomez Posted August 31 Share Posted August 31 Sponge filters are almost always low enough flow, you likely don't have to mess with the flow. I'd also not inject a 5gal with CO2, especially with smaller tanks because it is soo much easier to give fish CO2 poisoning if you accidentally dose too much. Also anything in a 5gal with CO2 injections should be done by someone experienced with CO2 in the past and lots of disposable money, as I don't see much point for a 5gal CO2 tank, unless it's a show tank that'll be setup for 2-3 weeks, as whatever plants you got will very likely quickly overgrow your tank. Also a tip on the airstone, new users like to have those really fine bubbles but you usually don't want that, you almost want bubbles almost like the ones without a airstone, just more fine, smaller bubbles; it'll give more oxygen in the gas exchange process.
