    Need some expert advice here. I have two different polyp colonies and for the last two weeks one hasn't fully opened. The only change was that a couple ballasts had burned out. The lights have been on track again for 48 hrs but no change?

    Salinity 1.025 calcium 490 PH 8.3 Alkalinity 4

    The other Colony is doing fine. Rotate feeding with zoo and phyto and a mix called snow something.

    Any suggestions? Thanks everyone

    Looks like zoanthids.

    Blow all the detritus off them.
    Check for critters as night.
    Zoanthid eating nudibranchs.
    Asternia starfish if witnessed on zoantids.
    Sun dial snails.
    Sea Spiders......

    If you increase flow have no bugs, and they do not open than dip them.

    Thanks for the advice! I have noticed the odd clear bug walking around. If they are in a higher flow area they'll do better? or the bugs wont like it?

    They will do better in higher flow. It takes waste products away better and delivers nutrients better also.

    Great, I now have two leathers, one is an toadstool and other is a finger. Any tips on these while you're helping me? Thanks

    They like to be in good flow and light.
