Hey Guys, I have a 50g moderately planted tank with CO2 injection. 1 airstone, and 1 sponge filter for aeration. I am in India where it's quite hot in the summer due to which my tank water temp stays in the 30 - 31c range (86 - 88f). I believe the tank water is not retaining oxygen because of the temp and my fish start to gasp within few hours of turning off the airstone after turning on my co2 during my lighting period. I was injecting 1 bubble per 3 sec which I know is very less for the tank size but anything more is stressing the fish. The tank is not overstocked. Currently, I have started to run the air stones with the co2 injection, I am wasting most of the CO2 due to the airstones but the fish seem happy and I don't see any other way out until the summer is over. Could you guys help with any advice that could help me optimize my CO2 or not gassing my fish even with such low CO2 levels?
