Thanks Brian! From the look of the chart I will probably have to set my ph
at 7.0. My Kh
measured 8.0 when I first set the tank up and has dropped to 6.0.
One more question. Will it be counterproductive to run an air stone at night when the lights go off? I was thinking this might provide additional oxpgen for the plants and fish at night. I don't remember reading on this forum where is advisable or not. Just a newbie trying to get answers. Who knows, maybe I can help someone one day.
