I looked into pickling lime and it sounds like a good idea, but Amazon is out of stock currently.
Do you know how much pickling lime to add per gallon?

Kalkwasser and pickling lime are both calcium hydroxide. They increase your pH but not your KH. KH is carbonate hardness, and it represents the majority of your alkalinity in a marine environment. Dosing carbonates and bicarbonates will restore KH, and carbonates are used to build coral skeletons.
I’ve had my coral QT tank running at an ALK of 6 or less for several months now and all sps are fine and growing. Even have a 20” clam in there doing just fine.
My alkalinity is perpetually low, at around 5.5. Without daily or several times a week dosing, it will stay that low. Dosing daily isn't ideal for multiple reasons, including messing with the stability. Will my SPS be OK if I just leave it that low?
