Hello,
So my lfs shop is saying the drastic change in salinity is probably what threw it off. They did a water test and all parameters back to normal including salinity. Here are some pics of the rapid tissue loss and wow it was very rapid took less than 24 hours.
My hours drive me crazy lol and I need to do something different I don’t wanna lose my tank. Too many close calls for me and I prefer to have no close calls.

Yeah in less than 24 hours I lost three sps, do to high salinity. So far all fish are fine rest of the coral are doing okay, but you never know with sps. The lps and softies should do okay. I’m super super sad that it wiped out my Oregon tort. Not sure where to get another one of them.
I'm really sorry for your losses. That is rough. I don't think that adding the salt water was the problem. In the short term, this would not have raised your salinity, it would have lowered it. As your system evaporated salinity would have climbed. The fresh mixed salt water would have been at a lower concentration than your tank. When your dad added that 5 gallons, it would have lowered salinity slightly, but not as much as if he had added RODI.Yeah in less than 24 hours I lost three sps, do to high salinity.

I agree with Brew. The proportion of salt to water is really what we are measuring. So regardless of the gallons, .25+.25=.25. And so in a not so precise way at all, if your tank was low 5 gallons, say 240 gallons at .28 + 5 gallons at .25 will net you something lower like .27. He would have added a lower concentration of salt to the higher concentration in the tank.
And my tank is smaller at 200 gallons but in my experience it usually takes extremes to effect tank parameters that quickly.
I’m definitely open to ideas and suggestions, it’s the only parameter that was off. Any other reasons why the three sps would do this? I tested everything, and they have been consistent. The only other thing that was low or changed was alk. It was an 8 that morning when I tested it and afterwards it was at a 6. But I tested the water and had to make sure because I wasn’t sure I was going to be home. Luckily I was or it could have been worse for me. Honestly I’m at a total loss as to why or what happened if it wasn’t the addition of salt water driving the salinity up.
Oh and the year 1955 just looks so fun and wow things were cheap back then. The style people dress if the movie is time correct is soooo neat.
. The one that bleached was right in front of the return lines. It received direct flow from the return pumps. The other two were on the other side of the tank, but not direct flow. The one that died in less than 24 hours probably shielded the others from the blunt on set. The other two on the other side are further down but also more in direct flow of the return lines than others. So many possibilities and will drive me crazy because one may never know.I would feel the increase in salinity during the evaporation process is a more likely cause. Do you normally let it evaporate that much prior to adding RODI water?I’m definitely open to ideas and suggestions, it’s the only parameter that was off.

This is confusing. Especially since it should have gone up when salinity increased with the evaporation. The drop is puzzling.I'd say your Alk at 6 is the most likely culprit. Why it dropped so low I don't know.
