Elegance coral

Hmm. I've advised to leave alone.

On the test kit's comparison cards, 2.2 is a value that's right in the middle of the 'normal' region. In fact, 4 is above the value given for 'very high'. I'm assuming I've got a scale wrong or something, but according to the test kit, the tank's water is fine.

As for the coral, apparently it's resumed all normal activities now that whatever it was has been expelled - it's stopped. Halides will be back on tomorrow however, so they're monitoring closely, and moving to as shady a spot as is possible at any signs of ill health.

Thanks to you all for your help!

 

My elegance had done the same thing right after I purchased it. After each time it did that it would be a little more bleached. Now it is slowly regaining it's color. I also had to shade mine due to the fact that I have T-5 along with my Pc's and the tank it came from only had Pc's. Hope it works out for you.
