I have a newer 10 gal tank (about 5 weeks). I used Seachem Stability and it is fully cycled. Water parameters are good,0-0-0 except my pH is 8.0. I don't know if I should use a chemical to reduce it or not. I've read that rapidly changing pH isn't good. The tap water here has a high pH so I'd have to continually use something if I decided to go that route. The only fish in the tank is a lonely Cory. I am planning on adding more cories but want I was hoping to have the pH down. Should I worry about the higher pH level? Thanks!
