We’re big fans of all the Red Sea products and use the blue bucket, Foundation A, B, and C, energy and colors. We’re finding as our 150 gallon tank matures (10 months old) we’re using more and more Foundation B powder supplement to keep Alk up. We try for 10 but we’re down to 8.6 and we’re dosing 120ml per day. We just increased to 140 to try to raise it but it seems excessive. Anyone know if the pre mixed liquid is more potent? We’re considering changing to coral pro salt too.
