Over the past few days some of my zoas have been closing up. The odd thing about it is, they are closing up in groups depending on color morph. It started with my green zoas and now my tubbs blue zoas. I don't see any parasites on them. I won't have test results until tomorrow afternoon. My salt mix is giving the new water a yellowish tint. Any ideas?

i am having the same problem with some of my hornets and they open and close from time to time. they can be finiky with water perameters and especially if your water is very clean, they like the dirty water. as for your salt i would test a new batch for everything and if it continues i would contact the maker, possibly a bad lot.
I did just get one of the modded impellers from Luke for my SWC 160 Xtreme Cone about 2 weeks ago. This started last week. My skimmer waste has increased since the new addition. I wonder if that could be the issue. I also replaced my carbon two weeks ago. The old carbon was in the reactor for a few months. Do you think the cleaner water mixed with the clearer water allowing more light to reach the zoas could be the issue?

it is a possibility they might be getting burned by the light. i would try turning the skimmer of at night or turning it down a bit. is the tank mainly lps or sps?
I would say coral composition consists of 15% zoas and softies, 35% sps, and 50% lps.

nice. the new skimmer may be making the water to clean and like you said along with the carbon the water may be letting more light in play with your skimmer and after any adjustment let them go for a few days. you may want to try to move the colony into a shadier area of the aquarium.
They are in the shadiest spot I have, literally not under the light. I have a 36" 6-bulb t5ho tek light centered over a 48" 75G tank.
I hung my fixture, so I just raised it as high as I could. I'm not sure how to make my skimmer work "worse" if you will.

tune down the bubbles just a tad so the column does not rise all the way. or close off all bubbles for a night to allow some waste to build up. what are the parameters?
I won't have them until tomorrow afternoon. Long story.
I just fed the poo out of the tank. I will also tone down the bubble production of the skimmer.

no problem but i would defiantly check into that batch of salt...what brand is it?
SeaChem Reef Salt. I just sent an email to seachem and made a new batch of saltwater to test as well. Hopefully it is just the salt playing tricks on me.

hopefully it is just the salt only because you found the problem and it does not leave you in the dark questioning yourself, hope everything goes well!
I am hoping this as well. I made 15G for a WC to do tonight after lights out, but I will be waiting until tomorrow when I test the new water. This is the first time I noticed the discoloration.
