Am I looking at precipitation?

I'll try and be quick and to the point lol.

Dusty water. High Calcium 520 (API) and little hard white deposits on the rock and back wall.

I'm using an aquaticlife 4 stage twist RODI and mixing with Tropic Marin Pro Reef. I don't even know why it's so high. Not dosing a thing but also no coral livestock.

Am I dealing with precip or are the hard deposits something else? Thanks all!

All I see are Spirorbid worms.
