Welso/trachy problem

[Michigan Mike]

Here's a pic when I first got it.

Here it is now, as you can see it is bleaching in the center or losing color and won't puff up much and never opens up to extend feeders. It has expelled xoo algae a while back but didn't think much of it at the time because most of all my corals have upon arrival, sooner or later.
Help!
Yes, I'm working on the cyno...errr.

So far I think its light shock and ALK swings, mostly light shock, everything else is growing,growing,growing, especially the algae.lol

I would guess flow or light - most LPS don't need a ton of light or flow. They can survive under modest tank conditions too (N03 ~ 20 ppm). The cyano could be a problem too. I don't know a coral that likes it My hammer actually closed for a while when I was battling my cyano in my first tank. It's not easy.

LPS are for the most part low to medium flow and for corals like Euphylia and such, indirect, irregular flow works best in my opinion.

HTH!

29g with 4x24 ATI Sunpower over it.
I just raised the light and will be using my dawn/dusk (blue plus x2) only, hopefully it will help.
I'm getting a pump for my two little fishies phosban reactor, just unsure if I should try bulk GFO or phosban or what-not sure what is best...

Low phosphate won't kill ur LPS. I don't think aiming for 0 will hurt either. It's your call.

Ya I just want to get rid of as much cyno as possible.

2 days of low light (dusk/dawn only) and today all the mouths where open and expelling xoo-algae or something, maybe a little color creeping in from the outside, not sure yet.
Gonna give it a couple more days.

Update, after only my dawn/dusk for a week and then swapping out the ge6500 bulb for a ATI Actinic bulb and placing the actinic up front under the welso and moving my toadstool down to partially shade the welso it has gained some of its coloring back.
Today I saw what appeared to be the skeleton I removed it for a closer look. Under a t-8 420 actinic I noticed it was some exposed skeleton, I bathed the coral in Lugol's solution and replaced it in the tank.
I will continue to keep light levels and hours down and hopefully the flesh will grow back.
Hers some pics.

Skeleton

Looks like the welso got worse last night , it had about 1/8th of it howling skeleton and last night it got worse.
Here's a pic...

What are your alk, cal, and mag levels?
