So, I've been in a little uh .. Situation like this for a while now. My beloved betta's are fine they're not sick or sore or unhappy it's just the water I'm worried about. It's unfiltered, treated and the perfect level when they're in then the next day the pH rises and I'm struggling to keep it down. I stopped bothering after a while because I felt as if I was harming my fish with the pH down.
Someone suggested it could be the gravel and then told me to put driftwood in with them? Another suggestion was leaves but I'm not entirely sure which.
Any other ideas?
Please don't be rude.
