Potassium chloride


New member
Does anyone dose Potassium chloride in there sps tanks?

Do you think it is important to do so?

Have you noticed any difference in your tank after adding it?

It is one of the zeovit products, I have read that it brigs out certain colors in low nutrient systems, and that low K can sometimes lead to the demise of certain sps in some tanks. I dont think there is a test kit available to reefers for KCl.

I have been using the Potassium supplement from KZ for some time now. I started using it due to fading colors in my SPS. All salt mixes except SeaChem Reef salt are considerably lower in K than NSW. I theorize in a low nutrient environment and with the addition of carbon sources for bacterial processes, the various trace elements, especially K become more available to be skimmed out, causing a rapid depletion of this element. I use 3ml daily in 340 total gallons. Marc is correct in that there is no commercially available test kit for K. I'm not familiar with Potassium Chloride, so I guess I didn't answer your question directly.
