Aquarium Advice Regular
after making a diy co2 and running it for a day or two my ph dropped from 7.5 to below 6. (also my kh is 240) I looked at an co2 calculator and it showed that that was way toxic. I took it out of the water for about a day and my co2 went up to 8.
Is that much co2 alright, how do i keep it from dropping, should i just leave it in there for a few hours a day or what?
