Hello all.
Not long ago I started injecting pressurized CO2 into my 20g planted community tank. I want to keep the CO2 on for 24hrs a day but can't because I've been having trouble keeping my Ph from falling below 6 with the CO2 on for only 10hrs a day. I can only imagine what would happen if I left it on all the time.......
My Kh is 50ppm so that's ok-ish....but with the Co2 bubbling away for a 10hr day (at less than a bubble a secind) the Ph drops to 6. Without the CO2 on the Ph is around 6.8-7.
I'm not sure if the Ph can drop lower than 6 becasue by the time it gets down to 6 the fish, understandably, start having some troubles, so I turn the CO2 off.
Shouldn't the Kh determine the starting AND stopping points for Ph?
Why is my Ph falling so low?
I guess that a hell of a lot of Co2 is getting dissolved into my water? But how do I decrease the amount dissolved? I've tried decreasing the bubble rate but that doesn't do it.
Oh and I don't have any buffers present either...
Hope you can help....and thank you for your patience.
