New member
Ok, so I have had a mester test kits for a while now. But that only test nitrate, nitrites, amonia and PH. I was wondering what other test kits I need to have for my rref tank, and what brand and where to buy them? Thanks!

This article covers all the water parameters, and the need for testing:


I check temperature, salinity, pH, and alkalinity every couple of weeks. Since I use a balanced additive, I only need to check for magnesium and calcium every few months. Phosphate and nitrate test kits can be useful for trouble-shooting certain types of problems.
