I have an alkalinity question. My tank is 65gal w/ 15gal sump. I dose twice a week with 5 cap full of reef carbonate and once a week with 1t of reef builder. Both are from Seachem. I have been doing this for a month and my akl is 2 – 2.5 mEq/L. I test with Instant Ocean Akl test kit. Exp is jun-07. can you help??
