I'm still losing montipora and SPS corals like red digitata in my frag tank while other SPS like purple stylophora are completely fine. I also have a Walt Disney frag in there that has proven to be unkillable regardless of the tank parameters. Early this year, I had large Alkalinity swings, which I corrected by bringing my calcium reactor online. I target 8 dkH and it's drifted slowly this month up to 8.5. Previously, I also had 0 nitrates and phosphates. I'm now maintaining both at about 10 nitrates and .1 phosphate and all of these have been consistent now for about two months. I've been reading that low potassium levels can create issues, but that potassium should be replenished with regular water changes. I'm changing 20% per week using Tropic Marin Pro. How many are testing Potassium levels periodically or should I just leave that to an ICP test?
Testing for Potassium?
