After watching my alkalinity slowly drop over the course of the past year just doing water changes I've started dosing to supplement the water changes. I got the BRS 2 part solution starter kit I've raised the alkalinity back up to the correct levels over the course of the past 3 weeks. I'm at a point now where I've pretty much nailed down the daily amount. I've been testing everyday calc and Alk and the Alk drops about 10 ppm each day but the Calc doesn't drop at all. I was under the impression that I would need to dose both but so far out of the 1 gallon batches I've made of Calc and Alk solution I've used about 100ml of calc solution and over 1/3 of the gallon of Alk solution. Is this normal? Since I started dosing I've seen an explosion of growth in my coral.
