Aquarium Advice Activist
I've got my DIY CO2 going pretty well now, and I'm trying to slowly boost my CO2 levels. I can get them pretty consistent with a heater on a timer, and alternating 2 liter mixes.
My question is this, how high do you all let your CO2 levels get before worrying about your fish? I'm trying to figure out what levels to shoot for.
I realize it probably depends on the fish, but I'd be interested in what you are doing as far as CO2 levels. And any problems with CO2 and fish dying. Chuck's planted aquarium says over 25 can be harmful to fish but it seems that people are going higher than that safely?
