My new salt water is cycled completely and has a tendency of keeping the pH at 7.8-8 i want it to be at 8.4 or 8.4 without chemicals. its a 55 gal with 50 lbs of crush coral gravel. the bag said stops chronic pH problems. Should i add 10 more lbs or what? theres 3 damsles in there now with a pocrupine puffer arrving around next friday
