KCl is 52.5% Potassium by weight, using this percentage and the dosing for anhydrous calcium chloride we are able to get a rough estimate for the amount of KCl to dose… just multiply the number given by the calculator for the anhydrous calcium chloride by .7 to find the amount of KCl to add.
Some users are using iHerb KCl with good results. We have not tried it, but if you are a bit skeptical be aware that Warner Marine makes a balanced ion potassium supplement that is not too rough on the wallet.
To get an idea of where your K levels are at, look into a test kit. Currently only Korallen Zucht and Fauna Marin make kits for this parameter. After reading reviews on both it seems like Fauna Marin’s is the easier of two to use… For an indepth look at the FM kit check out StonyReef.com’s write up.
Whichever K supplement you should choose, always start slow and observe your animals for any reactions.
