Once I add calcium to my 90 gallon reef/ 30 gallon fuge how long does it take to absorb into the water? When can I test it to get a accurate reading? My calcium dropped to 350 without me realizing and I want to get it back up asap! My tank is very heavily stocked with lps th only thing that seems to be hurting is my clam. Can I do more harm than good by raising the calc fast?
My alk is 9.3 and my mag is 1400 nitrates are 2-5
thanks
