My biggest question is why are you dosing your tank to begin with? Even some heavy SPS
dominate tanks do not require dosing, it is hard to believe most of the time that our tanks require it at all when a good salt mix will keep the levels where we want them to be with weekly water changes. A new type of salt with higher calcium, alk
, and mag might solve your concern without accidentally elevating one level too high.
Kent salt is one that has higher calcium and alk
, I use it and love it. Some research into it will find what is best for you, or you can simply ask of course. Hope this helps.
