Ok I set up a new tank and well I am new too lol. It is a 90 gallon bowfront. I tested my water in tank and also the tap and everything is 0ppm my only problem is the pH is 7.6. Now I am using Sea Chem Prime and was thinking of sticking with sea chem products and thought about using the neutral regulator. I am not sure how good this product is or if I should be using maybe a pH down. Any suggestions I would appriciate so much
