Zoa help,

Jdeleon · Nov 4, 2016

Im having a little issue with my zoas, little by little they have been vanishing. I really suspect my clown trigger doing it and in the process of trying to catch him. but something weird I also noticed is the base from the zoas that are disappearing are also separating off the base, like the gel that holds it together isn't quite holding and letting go. the zoas that disappeared left nothing behind completely gone like they were never there. Any thoughts or ideas would be greatly appreciated it.

By your pictures I can't see anything wrong with them.
If the fish is preying on the zoas please remove it now from the tank. If that is true you already know the solution!
If there is anything else eating the zoas you'll have to find out by observing.
The polyps could be detaching from the rocks because they are weak. Wrong light could be the problem. I said COULD!

I'm not going to discuss your light here because that is for the LED friends. I deal with T5s!
Your Mg is kinda high. Try to make sure the rest of params are good and stable.
I keep my nitrates and phosphates undetectable. Maybe you'll need some water changes???
If you have GFO remove it from the tank. Most people don't need it at all!!
If you use carbon just leave it in the system and don't touch it for now.
You'll need to write a lot so people can try to help you here... Give them all the details!!

Hope the LED guys to show up and give you some light!!!

Good luck!

Thank you sir, I did remove the trigger and so far things are looking better, this frag in particular didn't make. I did cut off a couple polyps before they all disappeared and they all seem to be recovering. Do you recommend any way to get Mag down other than water changes. I do water change every week and mag has never changed one bit.

I'm no expert but it looks like algae growth on a few of them and also looks like white spots (zoa pox). Especially visible in the last photo while zoomed in.

sorry but I believe that's actually flash reflection from the picture.

You've said: "Salt. .026" and I'm assuming you meant GS: 1026.
You could try to drop it to 1024.
Your Mg isn't that dangerous, but would be much better to keep it around ~1320.
Alkalinity at 8 is fine. I would suggest to keep calcium around ~420.
You need to check the Ca.
