Star Polyps Not Opening

I bought a small frag of green star polyps about 5 days ago and have yet to see them open up. The frag is about 1.5" square sitting under 32 watts of PC 50/50 light and 18 watts of actinic fluorescent lighting in my 10-gallon micro reef. The tank is happily supporting one small fish and a bunch of mushrooms which are spreading like wildfire.

The only thing that I can see that might be wrong with the polyps is that they look like they're covered in a thin film of hair algae. Could this be the problem, and if so, what can I do about it?

I've got 7 blue-leg reef hermits and a few snails in there that I'm hoping will clean off the algae, but no luck so far. I'm afraid I'm going to lose the polyps soon.

Okay, a couple things.
1.) get them as close to the lights as possible, they need a lot of light.
2.) make sure they have very strong flow. For example, when mine are open they blow VERY hard, it seems as though they would be damaged by such strong flow, but they love it.
3.) After adjusting them blow off any sedimentation and algae with a turkey baster.

Best of luck. If conditions are right they should open up within 24 hours.

Oh, on a side note, are you running any PO4 remover by chance?

i beg to differ. mine are at the bottom of a 24" deep tank with only 260w and are spreading like crazy.
definately lots of flow. they will open without the flow, but with flow they will spead and grow.
leave them alone the more you touch them the longer you will wait.
about a week ago i moved the rock mine are on around and decided to pick off the algae from them and they didnt open fully for three days.

they are weeds

Nope.
if you are not testing for PO4 you should. low levels help control algae. and stony polyps (star polyps are not stony) have trouble assimilating calcium when in the presence of higher levels of PO4. ( if i have erred in this statement someone please correct me.)

my star polyps came with a film of what looks like red hair algae. when covered my polyps won't open either. So I have tried a couple of different things that have worked, but the algae keeps coming back so its a maintenance thing I have to keep up with. But anyway I have tried just using some tube and just syphoning off the algae, but that is kinda rough on the polyps so i have switched to using a new toothbrush and just brushing off the algae. The polyps don't seem to mind the brushing too much, and they open up nicely within the next day or so. so just a thought for you to consider.
good luck,
Mermaid!

This is such a small frag that I'd be concerned about ripping it to pieces with a toothbrush. (The head of a toothbrush would cover probably 25% of it.) Every time I try handling it, pieces of it's purple skin flake off.

I agree with the turkey baster and flow concerns...it has worked for me...

I have found that star polyps can be tempermental at times. Mine will go a couple of days without opening, then be fine. May be an indication of water quality but not sure. Suggest that, apart from the flow concern, you stay the course and wait it out...
