Calcium/Alk for dummies...
I have an established fowler tank, and I would like to get into corals. I have Aquaticlife T5 lighting and protein skimmer.
The big thing I don't understand is Calcium/Alkalinity dosing.
I've read many articles on the subject, but I still don't have a clear understanding of which procedure is easiest and best.
When keeping corals, what parameters should I be testing in addition to Calcium and Alkalinity? I know Calcium levels will not rise if Magnesium levels are too low...do you always test for Magnesium?
Also, there are many supplements available for reef tanks (such as trace elements, strontium, etc), but how do I know if I what to add if I don't test for it?
