Major problem with salinity!

[reeferbuddy215]

So I have a beautiful well established 125 gallon mixed reef with sps, lps, softies fish and a dual 40 gal refugium with skimmer in sump. I came down the other day my father left the RO/DO auto top off on and diluted my salinity way below danger level. I did my best to make a batch but I barely had enough salt mix to get the salinity right my sps corals are fine but my huge Aussie branching hammer and another aqua blue lps branching colony and the 2 corals are slowly dissolving and my one lighting unit went from a bad fan. But I got a temp light fix but my lps colonies look bad I've been doing this for over a decade and they look bad but salinity is right back to what it should be

I suspect that the fast drop and then fast rise in salinity caused your corals to go into shock. I have never dealt with this- #reefsquad help

Not trying to sound rude but was there a question?

Yea. An extreme swing could be very bad for soft bodies.

How big was it?

 

[reeferbuddy215]

The 2 colonies affected we're about a foot long now they aren't dead completely just most of the branches are showing with minimal skin and the heads are closed

That bites. Might want to frag them back to smaller colonies. Assuming your salinity is back to normal they should recover.

This may sound out there, but I would also use vitamin C to help with the corals recovery. link it really works wonder with fish and coral health and yes it is kind of old school but so am I

Did you measure the drop in salt as you mention
