I use kalk with a reactor on my mixed reef tank. It's a 75gal tank not very heavy on sps, but I would like to slowly change that. I been checking my kalk for the past 2 month, my average Kalk is 7.7, it doesn't go below that and only goes past 8 after a water changes, which is 30gal twice a week with esv salt, but i will change to reef crystal. My question is, do I have to supplement Kalk with something else? I been reading threads of tanks with sps, and Kalkwasser doesn't seem the way to go to keep kalk above 8.
Thank you
