Is there a problem with these?

[SteveM10]

I've noticed that I have a few zoas that just dont look quit right and wanted to make sure there wasn't a problem with them. Please let me know if you see something in these pics that I should be concerned about. Thanks.

All my water parameters a very good. I did upgrade to MH about 2 weeks ago but these guys are at the bottom of my 110 and its 30" deep.

Overall pic

These guys havent fully opend in a few days.

The ones in the back havent opened in several days.

These just did this today.

it might be the MH's. i would blow that slime off those few bam-bams that are not open, and maybe slide the ones that are not openning in a shaded spot. what k bulbs are you running

ya like msman said those orange zoos have brown slime on them. you can scrub it off.
good luck.

2 250W 10K XM bulbs with 2 VHO actinics

Halides aren't an issue. I am fairly certain those were grown under halides.
Make sure to keep them in high flow.

well, the fellow up above me seems to know you. but i would say if there not new and you just swap lights it mostly the 10ks could try the shade like i stated before are put some black screen on the top

I'd use a toothbrush (new) to gently scrub that brown film off the colonies. I've seen that before and if left alone it will eventually kill off your whole colony. I'd also consider putting them in higher flow if at all possible. Best of luck!

I have had zoas do that when the salinity was off by a lot unbeknown to me as in too high.
