Bearchumjs said:Yeah. I guess some kinds of rocks can raise pH. I had gotten rocks from the river nearby. I'm going to soak them in water for a week and then test that water to verify that is what was raising my pH. I'm new to this too. I just learned that today actually. Rocks can raise pH, driftwood will lower pH. I didn't worry about my pH until every fish I put in the tank died. I have 3 left. The only thing that could be killing them is pH. All my other parameters are testing perfect. The fish show no signs of disease. It has to be high pH. Hopefully my last 3 survive!
That's interesting! I'm going to pm you so my questions don't hijack the thread..
