Hey there, I've been reading a bit on Red Sea's website and they say that for dosing via a dosing pump, their Reef Foundation A & C (calcium and magnesium) and Reef Colours B (Potassium and trace) can be combined. I've emailed them for instructions on how to do this (ratios etc), but I just wanted to ask here if anyone has done this, if it can be done with a DIY recipe or another brand's supplements, and if there are any pro's and cons to doing it this way. Obviously you would want to under-shoot demand for magnesium and potassium a little bit, and would require occasional manual dosing to even out the levels, but other than that I can't see any con's (if it's possible). Anybody?
