polyps wont open

[cgarsmokr]

I have 4 small zoo colonies that I bought last weekend and some of the polyps wont open.

ammonia- 0
nitrate-0
nitrite-0
phosphate-0.03
PH-8.3
Alk-8
calc-380
These are the only tests I have. I know calc is low so I'm going to add liquid calcium.
My lights are a Solar Flare 6 lamp T-5 set up and the zoo's are at the bottom of my 75 gal (20 in. high tank).
I need any help I can get. Thanks, Tim

do you direct feed or allow them to filter feed? what colors are they? how old is your tank?

[reefnetworth]

how high are your lights from water level? are any of them Actinic? or are they all T-5's?

What's your salinty?

Were they shipped in or was it a LFS purchase?

Where they dipped and/or acclimated? If so, in what, how, and how long?

Did you acclimate them with actinics only the first day?

Any other polyps that you already had doing this?

Any change at all in their appearance, do they seem pinched or flaking?

Discolored at all?

Current should be very good and maybe a water change after a week would urge them to open. I would just wait it out a couple more days, it might be nothing at all. I'm sure you have checked for possible hitchikers already.

It's not uncommon for this to happen, the delay in opening.

Netreefworth:
Regarding lights: 2 bulbs are actinic and the polyps seem to open up better when they are the only ones lit.
LAMPS:
1 GE 3000K
1 GE 6500K
1 Aquablue
1 UVL super actinic
2 Blue Plus (actinic)
The lights sit atop the tank until my bracket come in.
I let them filter feed.
Mucho:
Salinity 1.23
-I picked them up at Tropicorium in Romulus MI
-I acclimated them to my main tank water by drip method in a 5 gal bucket for 4 hours. No Lugols, freshwater etc.
-My lights were on a normal photoperiod of actinics for 1 hour then all lamps for 12 then actincs for 1 hour then lights out.
-These are my first zoos
-There is a white slime? on ona frag that I've been removing with tweezers.
-The colors look fine except the blue frag which seems more gray.
- I'll do a water change today and check the flow. Thanks guys. I'll see how that goes.
P.S. no hitchhikers noticed.

No change. I'll try a fresh water dip on a couple of frags tonight.
