Quick Zoa help question

[Craigdillman]

Calling all zoa freaks,

Hoping someone can help or got another idea, Recently my fire and ice colony of Zoas has closed up and been closed up for about 10ish days now trying to figure out why and see if i can get them back before they melt away like so many do.
Nothing has changed in the tank, still doing weekly or bi weekly w/c, parameters are in check
phosphate - .08 on the hanna
calc-420
alk-7.5
mag-1380
nitrates- undetectable

All the other Zoas close are open and fine the fire and ice ones randomly are closed ? not sure why? I tried moving them up to the close rock ledge thinking maybe a little less light and flow would help but I'm running outa ideas

Any thoughts?
