Water changes PH levels on it’s own, more-so when you have fish in them and feeding them, etc.
Turns out it was the gravel. I’m going to look into other substrate when I’m financially able, but for the moment it should apparently be fine.
The PH levels in my tank have suddenly become way too basic. It was neutral two weeks ago. I have a baby Molly and baby Angelfish in there without any plants. Does anyone know what could cause the alkaline levels to rise?
