Hardy corals not opening, help!!

[arriel69]

Hello every1,

I have no luck in getting my leather, mushrooms and star polyps to open. I had them 2 wks now. My water parameter are good with a little nitrate (10). I run 2-150watt MH with 2 PC. I thought it was my ligthing. I used to have T5 with 4x 54 watts for 110 gls. I now the flow is not the issue, cuz I have M40ecotech and 2 -470 flow rate korilla. Please help.

What are the exact numbers for your water parameters?

Did you acclimate the corals to the new lights?

What are the exact numbers for your water parameters?

+1, betting your salinity is out of whack as well.

Thanks for all the replies and apologize for late reply. Anyway, information provided as follows: NO3-.05, PH-8.3, Salinity- 1.026. Just had WC last Friday. My star polyps open partlally, but my leather and mushroom still no luck. All my turbo snail died. Don't know how long now. I had 2 peppermint shrimp, 3 hermits. Do I need to do another WC to make sure that my water will not contaminate. I dose my tank with MB7 and Reef biofuel.

No, I did not acclimate my MH when first got it. I guess it's too late to do that now. But after 2 days I got it, someone told me to turn on the MH only for 4hrs for 1week and I did that.
