Zoo's not opening

[reeferRob]

Many of my zoas and my clove polyps are not opening for the last week or so. The rest of my livestock seem to be doing just fine. I check my parameters weekly andd they are always in order except my nitrtates

PH 8.2
SG 1.024
Temp 81
Amonia 0
nitrites 0
nitrates between 40 and 80 (High I know but I have yet to figure out why, I don't have a TDS meter so I ordered a new set of filters for my Max Hi-S 35 RO/DI. I've removed all sponges, and filter pads, cut back on feeding to the point I fear starvation. Clean skimmer weekly - runs 24/7. I have Cheato in sump, about 200lbs of LR w/lots of corraline. I do weekly 20% water changes
Ca 410
dkh 10.6
Mg 1350

I run 4 - 96w dual actincs 12 hours/day, and 3 - 150w 10k MH about 5 hrs/day

what is causing so many of my polyps to not open? Any ideas?

And I thought zoo were for kids!? Very forgiving of water quality? A beginner coral?


Thanks

AAHHHH CRAP!!! I was in reef central and looking through the Zoo forum and found this http://www.reefcentral.com/forums/showthread.php?s=&threadid=691978 Many of my colonies have developed these white spots, I was assuming it was flecks of sand. I hope I don't lose all of them

I had zoanthid eating nudis a while back, and they really blend in well. A FW dip and scrub made them come right off and haven't seen them since. You might also check for them.

I did see a few days ago a slug looking critter about 1/2 to 3/4" long going across my glass. It was a whitish color with like small feather-like appendages or tentacles on it's back. Dunno what that was but it looked harmless so I left it, no idea where it might be now or if that is the same thing. In fact I think I read that thread and it looked more like the critter you (or whoever it was) was told to eat .... ahh hell I don't remeber now!

Now I remeber it was a berghia nudi for eating aptasia, guess that wouldn't be the same thing you had. :lol I"M SO CONFUSED!!! :(
