Issues with my leather corals

[Gary Passwaters]

So I’ve been having issues with all of my leather corals since my heater broke about 6 months ago. Nearly lost everything while I was on vacation. But now everything else in my tank has seemed to recover but my Kenya tree, cabbage leather, and toadstool. Not sure what else I can do at this point and not sure if anyone has any ideas. All 3 have neither increased or decreased in size at all.

I run carbon and my tank parameters are; temp 77, nitrite/ammonia both 0, nitrate 2, ph 8.0, calcium 500, magnesium 1350, alkalinity 7. I have 2 ai hydra 26’s over a 55 gallon tank. Skimmer and charro in my 20g sump.

Maybe particulates in the water irritating them !
I've had that happen and ran floss to really clean it up (even though I thought it looked clear before I did the floss)
Boy, it made a huge difference!

Well I’m going to add some to my sump and see what happens
