Xenia and Zoa not looking so hot..

To understand what is hapening to your coral, it is best to first get the water quality perfect and if that does not solve the problem, then maybe try a dip.

Check if there is no parasite. Because the xenia is also not looking good, this makes me think that it's the water quality that is the problem.

K thanks will try this, I thought maybe part of the problem might be cause they used to be under compact fourescents, and this it when it started, so I switched to t5s

thats very possible, corals need tme to adjust to new lighting do it slowly

I noticed in another thread that you mention using treated tap water. How long has your tank been running & how long have the corals been in there? Even though whatever you use to treat the tap water will bind the chlorine, there could be traces of other elements building up in your system that are making the coral go funky. See if your water provider (city?) posts water tests online and check it out. Should be a good list of what's in your tap water & at what percentage. Even a trace of copper or some other metal not harmful to us, will eventually build up in your system & can affect invertebrates & corals in particular.

My advice is to start using pure water regardless.

Yeah I have checked nothing really online. I have tested it though and everything is 0 aside from ph of course but the tank it was in had some higher nitrates around 20 ppm still not deathly high but getting there the new tank its in is at 0 so its not getting any worse now, but i just put it in yesterday, so it hasnt gotten any better yet either lol

try moving it to the bottom of your tank in ambient lighting and see if that helps i believe you have some light shock happening plus the move to a new tank

Hmm, too bad you can't find a water report. Here's one from Greater Vernon. As you'll see there are some things in there that we actually need in our tanks such as calcium & magnesium. But there are also traces of undesirables that are just too risky IMO to keep feeding into my tank year after year. Come to think of it, I don't really even want to drink some of that stuff myself, even though according to the authorities it's at safe levels. I've been using RODI water for my tank for well over three years now & tapping off RO water for coffee, tea, drinking water as well. Great investment.

Testing for the standard parameters like nitrates, ammonia, phosphates, pH, calc, alk etc. is all well & good, but we don't generally test for copper, arsenic, aluminum...... so saying everything is zero is fine, but what about all the goodies (nasties?) you can't test for?

lol holy ****. I see what you mean by not wanting to drink it, sure its at low levels but still, arsenic, mercury? MAN!

So if I got this right it was in another tank with PC light and unknown water parameters, then they were moved to another tank after they started to close and they have not open yet under the T5 and new water condition.

That's a lot of things to adjust to for a healthy coral, even more so for a sick coral...they will need time and a slow acclimatation to the new light.

They might come back, they might melt..hard to tell. It will probably take some time to come back if it does.
