Hey guys,

Having a little trouble with my 90 gallon.. It's cycled completely, no ammonia present, temp. around 78, aquarium sand as substrate, water changes once a week, yet my PH is high, anyone know why?? I'm thinking its the presence of the nitrates in my tank but i'm not sure. Any help would be great

Check the parameters of your tap water first. That is the basis of everything.

Actually, high nitrates would lead to lower pH.
