I recently ran out of Pohl's K-Balance Strong, a Potassium supplement necessary for Zeo systems. The old bottle had a price tag of $69.99 :: attached to it, so I was not eager to buy another bottle. After scouring the boards on RC, and a few other sites I found some great info. Both Brightwell Aquatics(Potassion) and Warner Marine have come out with cheaper K+ supplements than K-Balance, but the cheapest I could find being used in tanks(with Randy's Blessing) was Now Foods Potassium Chloride from iHerb.com. One bottle from iHerb($3.76) has about 3 times as much Potassium as a bottle of Potassion($9.69). That comes out to be $.03 per gram vs. $.24 per gram. Korallen does not publish their K-Balance Strong info, so I have no idea how much K+ is in a bottle.
Potassium Supplement Calculator(Use Reef Calculator)
"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." Remember this needs to be slowly added over many days, and not all at once. No more than 10ppm per day.
Notes
I use Reef Crystals which has a K+ level ~250ppm. So when I do my water changes I make sure to add enough K+ to bring it up to ~390ppm.
If you find your blue corals fading like I did your K+ might be low. Since I got my K+ levels back to NSW levels my colors are returning.
