My acros wont open and my water is perfectly fine! - Page 2

Do u have any fish in the tank? My best guess would be eighther your corals are starving or u may have pests. Those are two areas I would definitely focus on.

Are u relying on water changes to keep your params in check? Stability is key & relying solely on water changes usually isn’t good enough to keep everything stable, specifically alk.

The first things I would focus on is pests & stability. If those two check out then focus on if they may be starving

Ammonia-0

Phosphates-0
Calcium-360
Alk-dont remember but it was good too
Salinity-1.024

My tank also has good flow and i use ocean revive light.

You need to do tests multiple times. It’s impossible to know otherwise. Stability is more important than the actual parameters..

Also nutrients shouldn’t be 0. I keep my sps tank at 5ppm nitrate/0.2 phos.

Calcium looks to be a little low, also I'd increase the amount of light you are giving them. What do you use for flow? And I would suggest sticking to doing water changes. On a 20 gallon tank they are simple to do, plus doing a dosing only no water change tank is much more work intensive and best left to those that have experience. Even those with experience tend to slowly move away from water changes, not just try doing it from the start.

Hand dosing for alk and Ca? And sometimes not for 72hrs? How big are the alk swings? Could be a problem there too as stability is really important to SPS.

I agree that salinity, Ca, NO3, and PO4 are all too low.

Another question would be, what kind of acros are they? I know a lot of mariculutred and fresh wild acros usually don’t have good PE.
