Zoa issues

[GerberGirth]

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:

Nirtate 20
Ph 8.1
Salinty 1.025
Alk 8.6
Cal 460
Mag 1380
Po4 0

I mean, if you believe po4 at zero to be accurate that might be it (strictly going off what you posted). Might start there imo. They like "dirty" water from my gatherings... Nitrate (again if accurate) seems to be in a good range...

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.
Assure salinity and Phos has not become elevated. Temperature and pests are often blamed. Spiders although super tiny can be spotted going into heads of zoa and if you have asterina stars- they are prime suspects as are rabbitfish and butterfly fish, filefish and dwarf angels.

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.

Not sure what they are called but when open are a really nice dark green color.
