High salinity tank corals affected

[Hungriee]

Does high salinity in a tank affect corals? Most of my zoas look like they are peeling skin off the polyps, my LPS (acans, blastos) some polyps are seeing the skeleton. At first I thought it was calc/alk swings then I measured my salinity w/ my refractometer and wow it was 1.035. I quickly did a water change and have bought it down to 1.030. Tonight I'm going to do another w/c to bring it back to 1.026.

All livestock (fish) are doing fine, just my corals are all taking a hit right now.

Yes many, if not most, corals are adversely affected by high salinity. Knowing nothing about your tank or your system, I'm going to guess that you supplement Alk. and Ca. via B-Ionic or other 2 -Part methods. One of the byproducts of using this method is a slow increase in salinity. You need to monitor it regularly and compensate with fresh water additions.

Bring the salinity down very slowly.

I use C Balance Part A&B method, that's probably whats causing the salinity increase. Seems like my corals all took a hit, when the salinity gets back to normal, what are the chances of the LPS healing? Most of my acans have darkened and I've noticed the skeleton rims now - or should I just throw these pieces away to avoid any further toxins in my tank?

do not bring the salinity down too fast, like 30 to 26 in one water change is too fast. try it in 2 water changes

Yea, I lost a ton of SPS corals (this is before I invested in a refractometer) to high salinity. Surprised your fish are doing fine!
