I just changed my betta because I’m treating him for fin Rot. I did a 100% change and maybe 3 h later I did a test and saw his KH and PH are low. PH 6.0 ( normally 6.5) and KH 40. I got nervous cause he was swimming and flaring and the all the sudden is on the bottom laying down. He’s exploring and swimming right now. ( maybe I’m over reacting....) I also just fed him and he about jumped out to get it. Some one tell me I’m being to protective.
