I really was thinking of buying that tropic marin all for one reef thing but since Im only planning to buy the Alk tester for now, should it be okay? Cause dosing it while not knowing the other elements' parameters are scary to me...
It's best to have a calcium test on hand with all for reef as the alk changes slowly when dosing with all for reef vs the calcium is immediate. As for the other things in it, I've dosed a gallon so far of all for reef with a single 5 gallon water change on my 75 with no issues
