My pH has gone up from 6.8 to 7.6 over the past month in my 10g tank. The plants have mostly stopped growing but the Pristella Tetras are well.
I'd like to see the pH back around neutral but I don't know what caused this change and I hear that things like PH Down are a big no-no. I don't have any rocks in the tank and I have bogwood.
Can you help me work this out??
