lol sounds like everyone has different reviews.. i tried to look up reviews on them from google, but nothing much comes up.. right now i am using Red Sea Marine Lab... im gonna finish using it all up, then get the salifert!
but i do need a good calcium test kit now... so i will probably order salifert...
In the event I have low calcium, what is the recommended way to raise it?
I have read about some calcium raisers that end up lowering or altering other make-ups of the water..
