Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Thanks Ralph, everything was great!
My wife and doctor want to thank all the photographers for helping to make their case against me; my diet starts this week. ::)
Cut your losses and just go with new ballasts from somewhere other than Homby/Aquatraders.
I had a bad experience with them on a T5 strip light where the original ballast and the replacement died within days.
They have a long, ugly history. Stay away from them!
I do all of the above: SeaSquirt, turkey Baster, large syringe with some rigid tubing, and feed the whole tank and let them get what's floating.
In a real reef there is enough food in the water column drifting and swimming by to let the coral feed themselves, but not so in a closed system.
LPS...
Looks possible to me.
I know my candy canes would occasionally go through a cycle of shrinking to almost no exposed tissue for a few days before an extended period of growth and splitting.
Sounds good on the carbon.
I would dip that colony. IF everything else is OK it's unlikely that it's parameter related.
Is there another coral close enough to that section to be attacking it?
Alleopathy is a possible cause.
Carbon works fine if you change it on a reqular basis.
Jceli how often do you change the carbon, how much do you use and how is the tank water processed through the carbon?
That's a great idea Ed, but a bad time at the moment. I will be able bring a 4ft VHO setup after I do my 180 upgrade as I will be shutting down my 55. Hopefully by September.
I have the T12 VHO's and only keep easy SPS in the top 8" of the tank.
Since you want to keep more SPS than the others I would go with T5's overdriven with IceCap ballasts and don't forget the fans. Of course once you need fans, in my mind you might as well go halide and you won't have to...
