reefers best has 420ca and 11dkh alk so i doubt a 10% WC is causing your problem, i am dosing 60ml/d ca and 80ml/d alk using Randys 2 part instructions in a 90 gal lps reef and my params are very steady ca 430 alk 9dkh, could your test kits be screwing with you? what kind are they?how are you mixing your chems? i've used BRS chems with no probs, i always follow Randys 2 part recipe when mixing and bake the baking soda if not using soda ash for alk(baking the baking soda turns it into soda ash)which has a higher ph.
