Only started adding Kalk in the past couple months or so because my phosphates and nitrates shot through the roof when my large yellow tang died and I couldn't find the body. I have been having stability issues for well over a year and a half basically since I started dosing nitrates.

I added the Kalk to help stabilize the phosphate. I didn't want to have to get too aggressive with the GFO.

I have added Kalk before without too much problem.
