Bryosis & Red Caulerpa Ques.

[Mr aqua]

hi everyone - i seem to have gotten BRYOSIS in my nano-tank. it isn't a huge problem but i don't want it to if u get my drift. so my question is what can i add to a 20gaL that will eat BRYOSIS? SECONDLY - i have never been able to deep RED CAULERPA in the tank. i purchased a nice peice of LR with some RC on it, after a few weeks it turned brown and shriveled. the peice was placed high in the tank with 130watt PC's. did i nuke the stuff or what?thoughts/opinions pls - thanks.
