As it is mostly just frags left, and most of the most valuable ones have died, I think I am going to try and get rid of all the remaining Acroproa and try to go acropora fallow for the 10 weeks. The difficulty though is how to get rid of the encrusted portions of the acro frags so that there is no longer any food for the flatworms. Any ideas in this regard?
There are some great locals that are willing to take frags while I work on cleansing the tank. I think we all need these lessons in order to learn better practices in the future. I'm just lucky this happened to frags, so I only lost money (not money + much more time).
