Lee, they are mostly medium size pieces, with the largest maybe being 10". They are not covered in pests.. I pulled them out of my sump and I have not seen any bad things come out of them.

Steve,

I can't call you from work, the Blueline and skimmer are sold. I still have the PC lights, 58 gallon show tank, two Hydor #1's, my metal halides, my 85 gallon freshwater and the liverock.
