Hi and welcome to R2R.

Going to move this thread to the Chemistry section.

Assuming you do not dose, it will drop on its own. That would be my choice over adding acid to lower alkalinity.

High alkalinity is fine as long as you have adequate nutrients in the water, but your nitrate is low for that and feeding more short term may help (or dose nitrate)

Yeah, I agree. I lose about 1.2 kKH per day in my 55 gallon mixed reef. Depends on what you have in your tank, however. I have (15) corals, including (4) SPS and (4) LPS. The rest are some leathers, mushrooms, and other softies. Good luck!!!

What fish do you keep in that tank?
