Subtle light and moderate flow is best to keep mulm and sediment off of them. If you give them gentle bursts with a turkey basters, you may notice this dust which irritates them. Sad to say is often when they are melting, they are dying but can be turned around. It can be to too much light or water flow, sudden change of parameters and even use of vodka or carbon dosing that reduces nitrate quickly.Sorry for potato quality of my phone and filter. These two zoas been closed up for a little now. The only thing they have in common is the yellow/purple zoas are next to them. The rasta was open all the time and now this. Parameters below:

There isnt any dust really coming off them just started to look like this. Kind of sad if they die as they were my first corals. Everything has been stable for a year now but guess time will tell. You think I should try to dip them?
Those filaments may be irritating them and I would place frag in a container of tank water and scrape them off with a small screwdriver or edge of a paring knife
Try getting rid of tbes first which just mentioned. You can dip in 3% peroxide also which often gives them a boost
Went ahead and scraped them off and will dip later tonight.
Any idea as to what those filaments are? That frag had a ton of GHA when I got it. Cleared up but assumed it was left from that.
People call them tree branches LOL but tube remnants and cant think of name but found often in sumps
Not sure what they are called but when open are a really nice dark green color.
