Just did a ph test two days after a 30% water change, and my ph was super high in my ten gallon. at least 9.0. Immediately did a 50% water change.my tap water is 7.0 so it can’t be that. My betta fish is doing fine, no signs of illness. I think it’s possible that because i have sooooo many plants (tons of floaters, dwarf sag, a medium sized crypt, a few small java ferns, ludwigia, pennywort, four anubias, and a trident fern) they might have been sucking up all the carbon dioxide and in turn making my ph super high? Idk. How can I keep this from happening again? I have a lot of almond leaves in my tank, but they clearly aren’t lowering ph. I took out a handful of floaters but there’s still a lot, and i love them so i don’t want to get rid of them. how can i combat this?
