Zoas closed up after day 1

[mr. penguin]

So I got a new zoa piece Saturday. I floated it for 15 mins for temp and then ran drip acclimation for an hour. I put it in my tank and it opened fine. It also opened Sunday. However, it didn't open at all yesterday or today. All of my
levels seem fine. The exact same thing happened with a hammer coral I got a few months ago (opened for a day or two and then never again).

I have a 28gal euro with a Current USA Marine led light. Could it be the light?

I moved the zoa to my nano tank and will leave the lights off to see if it recovers. I placed it in the sandbed just as it was in the store and then tried it 1" up on a rock.


Please help! I can't keep losing corals after 1 day!

Did you start it on the sides aways from being directly under the LEDS to give it some time to acclimate to your tank and lighting scheme.

No. I was worried it the lighting so I kept it low in the sand bed and tried moving it around, but it never opened

meaning from the start, put the in the bottom corner till they acclimate then slowly move them more under the direct lighting then higher as time goes on and the Z's show positive and happy with the movement.

raise your Alk to 10-10.5...if a big difference from your params now,,do it gradually if needed..
