Yesterday i did a 40-50% water change and switched from all gravel to 1/2 sand in my 29 gal. I used petco brand white sand. I actually covered a lot of gravel to try and maintain more bio filter. I did kick up some gunk so today im testing. Everything is good except my ph is whacky and i do t know why. With api test strips i get a very low reading with api master test kit it is crazy high. Most fish seem fine my bn pleco is MIA and my cory seems stressed. Ive triple checked and im using imagitarum aquatic substrate not crushed coral or another ph raising thing. What do i do?
