We have a RSM130 stocked with LR/LS, all sorts of corals (soft, LPS, SPS, etc), a few fish, some crustaceans, and of course a CUC. Anyway, we are ALWAYS adding Calcium, Buffer, and Magnesium. We do weekly 15 gallon water changes and use Oceanic salt. We've tried Tropic Marin and Instant Ocean salts to see if that makes a difference. We've also tried different brands of additives and are now using Reef Advantage. It seems that our Alk will be good one day and then three days later it is down to 1.5! I am so frustrated! Any advice would be GREATLY appreciated!:smack:
