You are dosing just over 1 dKH per day. Unless you detect signs of precipitation such as hardening sand, I’d just try dosing more each day.

After many days dosing redsea foundation B, i used baking soda for 2 days. Now Kh is stable today (9.0 dkh). I wonder if i should continue dosing baking soda or what else? Tks!

if precipitation is a possible issue, you can use a variety of different low pH diy or commercial alk supplements.
