Alright, so the plan is to have something to control the grape caulpera. I would like to save my nicer macro algae.
I was reading around and a recommendation is emerald crabs. They are hit or miss, but at least its a chance. So, Im thinking one or two emerald crabs, and then when they get older I would trade them in. Although having crabs in the tank would just be so cool.

I'm going to do more research to see if it is worth the risk.
If that doesn't work, I will seriously consider a tang, but I really don't want one.
After that, Im going to tear everything down and sell or trade all my LR but keep my coral and just start over with normal LR and NO CALPURA.
Any advice ?
