How much aeration is needed at night to gas off the co2?
Hi, i have this newly rescaped (the tank had been running for a month previously) 30 gal aquascape tank and currently do not have a solenoid valve (im currently ordering it as im typing).
I had the co2 flow controller set so that no co2 comes out at night for the whole month. But there suddenly seems to be something broken inside when i checked a minute ago and now i cant set it so that there would be completely no co2 coming out. I've already set the airstones and the aeration right now is probably so high that even the tetras that come near the airstones gets swept away instantly. I wouldnt worry about the fishes getting stressed as they can easily find a spot with no current.
Now here is the question. Because i dont have my solenoid valve yet, how much aeration is needed so that its enough to gas off the co2 and make everything safe? Im also worried about the amount of aeration needed because the co2 drop checker doesn't seem to be turning blue. Pls reply asap if you have any answers or suggestions.
