What parameters besides PH and alkalinity should I be testing and what kits do you recommend to test all the parameters?I wouldnt start dosing until you start testing for those parameters, could do more harm than good. Testing will show how much to dose a day. I like using 2 part from BRS but mixing is a little hard without proper jugs, Tropic marin all for reef seems to be a good all in one solution once you start getting corals. If/when dosing with a dosing pump, i find 2 part super easy to use on its own. The alkalinity part of 2 part needs to go into a super high flow area or precipitation will occur.
