Why not use a less expensive product like Reefbuilder to get your alkalinity up then use B-ionic to maintain it? For example, assuming 55 gallon of water, to get from 5 to 9 dKH, you'd need 425 ml of B-ionic alk, according to the reef chemistry calculator. That's a lot to make up. Using, Reefbuilder you'd need 4.1 tsps. A lot cheaper if I am not mistaken. Anything wrong with this approach?
