Alkalinity

Have a quick question if my alkalinity is 12dkh and I want to drop it. If I let it drop naturally as to the corals taking it in. Will it start to kill my sps or would it be fine

Letting it drop naturally is good. Why is it so high? What salt are using? You can safely lower it .5 dkh per day.

You must mean 12 dKH, not ppm. Simply allow it to drop....12 is on the high side, and letting it drop will be just fine. I wouldn't allow it to drop below 7 dKH.

I was dosing to much kalkwasser corals were taking in enough so it just kept raising it. So I recently stopped the kalwasser and letting it drop naturally. Just seen today the green slimmer didnt have much polyp extension bits all others looked good. So didnt know if alkalinity going down was effecting it or not

Tropic Marin reef pro test at 7.4-7.5 dkh consistently at 1.026 SG for me, I test every batch and dose it to 8.0 dkh. What dkh were to trying to get to out of curiosity?

Test alk daily. Stop Kalk til desired dkh is achieved. Most of us with sps test dkh daily..

8-9 dkh

Instead of stopping it right away maybe half the dosage of kalk and then in a week test what your alk is at. That way you can go slower on the drop.
