Food, because the fish beg. WC's because the corals are prettier when I do, and my supplements are replaced with a Ca reactor because I'm too lazy to mix up a three part regularly.
I put my hands in my tank almost daily! :bigsmile:
I'm an Alk, Calc and Mag doser. Alk and Calc get added three times a day with dosing pumps. Mag gets dosed when needed....about once a week, manually. Other than food and a 15 gallon a week water change, nothing else gets added. I am a firm believer that if you dose it you better be testing for it.
After testing i dose what my tank is lacking. Usally that would be calcium , Magnesium and alkalinty. Most of the other goodies are in the salt mix. But you have to test before adding.
