Why won't zoa's and polyps open?????

[jarrett shark]

Well its been about 2 weeks since I did my tank tranfer from my 72gal to my 220gal. Everthing went perfect with no cycle! All levels are perfect.
Since I did this tranfer my polyps and zoa's won't open?

I did upgrade my lighting from 2-250w MH - 3-400w MH. and t5's to VHO's
All my other coral looks good since the tranfer. I thought maybe it was not use to the new lights but this past weekend at the swap I buought some zoa frags and they also will not open. I even put the zoas and polys under a rock so it will not get less light. Something is bothering them and I can't find out why so maybe somebody else see's something I dont?

I tried reduce my water movement one day and still the same results. Increased water movement and still the same.Did a 35gal water change the other day and the same. Put MH on for only 6hrs a day and still the same...........
Don't see any bugs and no fish a messing with them
My sps love the lights and my other coral are also bring out there color and look greater.
The only other coral that I tranfered that was not doing great was galexy.I just went thru old pics and thought the bigger tank made them smaller but guess not, they also look not right.

So before I go crazy do you see something wrong,
The first 3 pics are old tank and last pic
The 4 & 5 are the new tank with same coral except gallexy in witch does not look the same size also. Looks 1/2 the size it use to be.

If anyone wants to frag some of these and see if they open in there tank feel free to come by and take them.

My fish look like there are in haven and are eating like pitbulls.

Amonia= 0
Ph= 8.1
nitrate= 0
nitite=0
calcuim=430
alk/dkh= 8.5
mag=1375
salinty=1.025
phos=.01
I feel that I cant get Alk and ph up?
I am about to hook up my calcuim reactor but was affraid it might bring my alk and ph down the first week setting it up.

bump Anyone??????

I dont now but now my xenia's are closing 3/4 of the day the lights are on?
do you think I should of went with 250w MH instead?

Was the 220 a new or used tank? Did you add more live rock or dead rock?

[jarrett shark]

it was a used tank, I added more live rock

i had the same happen to all my zoos when did my tank transfer and they never recovered they just melted away. if yours are not melting i would have to say the increase in light is probably to blame. have you tried putting them in some shade to see if they would open? going from 250s to 400s is a huge jump if you did not take the time to acclimate them to the light.

good luck and i would deffinently try moving them to some shade.

I have had this happen to me as well. When my tank stabilized and sps and clams were flourishing, my only casualty were my green zoos. Before they melted, I put them in my daughter's (man it's nice to have an excuse for another tank) 29 gallon softie tank with two clownfish and they've since recovered. I never could figure out how mixed reefs worked well. I think you have to have a good balance of both to be successful. Remember that zooanthids are collected from much deeper water than sps; so light may definitely play a major role. Maybe try target feeding them with your favorite mush. Just my two cents. No science...just what worked for me. Then again, I have two 400 watt 10k bulbs and two 250 watt 10k bulbs (two hours midday) that illuminate my 72" 150 gallon. Something's gotta give right?

Should I try to put them in my 60gal sump with about the same flow as my DT? it has a PC light and my Muschrooms seem to open in there? Or should I try to put them in my fuge were water flow is like very little

Good thread, so I think the lighting is #1 because
1) zoas wont open
2) polyps won't open
3) toad won't open
4) finger leather won't open

I think maybe there is stray voltage, buying a ground probe today
idone is high,buying a test kit
or I have bugs that I can't see, doing more looking today

400w are strong bulbs!!!!!!!!! I sure did not do my homework
well its been 4 weeks since the upgrade and now some zoas/polyps are starting to open slowly today, I still have 2 toads that will not open?Melted lots of mushrooms, Lost some sps that was close to light. My frogspawn looks like when the lights are off.I did put a window screen over the tank to reduce light today as per member "insane". I also moved rock around so I have shade spots. I am afraid to buy new coral until this coral I have starts to grow.

how long do I keep the coral that wont open in the tank?
what does it look like when its dead? Some coral look like it peeling a layer off?
