a question for everyone
about 2 weeks now i have been mixing in a cup

(3tsp CaCo3 99.5% USP grade 5ml acidic acid99% some water) a day later into the mix about 80% of the calcium dessolved. PH readingof the test cup was 8. i have made this recipe 3 times and added it to the reef (40glns)
my calcium in the reef tested at 300ppm before i add anything. after the recipe been added reef calcium tested at 520ppm and 26DPH is something wrong with the tests or does this sound right with no precipitation
also thinking of purchasing magnesium chloride anhydrous99% to bring magnesium up to reef level 1350
all my corals are doing better than fine soft LPS and SPS
