Coral ID and Advice
 

Hello,
I have been having some problems with some of my corals in my tank. The ones that are not doing well are the dragon eye zoas, some sort of montiporas and my little baby plate coral. Xenia is not working out in my tank.

Here are some photos of the troubled corals, and one i need an ID for.
Green Digitata, seen in the top right of the picture is bleaching. I also need an ID for the coral in the very center, somewhat blue and green.

My plate coral, it seems to be stressed with some bleaching

***Montipora encrusting coral, not sure of its full ID but it once was purple with bright green spots, now almost completely white.

***My green dragon eye zoas, added about the same time as my other zoas but there is a difference
Before (notice the polyp loss compare to it now)

Yes, i do have alot of green slime algae, and i am getting very small spots of red cyno bacteria, starting up my phosphate reactor with some GFO. The green slime algae is disapearing more and more everyday. Im going to go ahead and try to propagate the coraline algae i have.

I also used to have xenia stalks, it never grew. Would open on its first day then close up and never open again untill death. Any idea what to do?

My ph is 8.02
no nitrates, or ammonias
10% water changes on a weekly basis, i use tap water though.
The tank is over 2 months old with no fish loss, and 1 dead xenia and 4 snail losses.

A friend suggested to dose with Lugols solution, i had potassium iodide in my closet so im going to add some of that... lugols solution is composed of iodine and potassium iodide.

Will dosing with supplements help? I have all the ingredients for a 2 part solution of, calcium and magnesium sulphate and baking soda. With light dosage.

Thanks, i hope someone can help me out

need bigger pics for id

sure one sec

It looks like its a little Florida Ricordea

You might want to look up montipora eating nudibranchs and check your monti's

How's the waterflow in your tank?

I have 15x turnover rate. 600gph on a 33gal.

Ive never seen any montipora eating nudibranches.
