Since I switched to Tropic Marin Pro salt, my potassium has been elevated. I now have approx. 440 -450 in my ICP tests. Do any of you have the same high potassium values with TM Pro salt? The problem as I see it is that it can inhibit growth and darken my corals. Many of those I know who also use TM Pro salt see the same thing. I have tried measuring with the TM Potassium Pro test kit, in freshly mixed salt water that has been circulating for a few hours, the result is between 460-470 mg/l. I measure at 35 ppm. The test has been carried out several times with a test kit that is not too old and has of course been carried out correctly.
