I ended up hitting the fungus and mushrooms with marine epoxy clear. They look good, just wanted to be sure as I wanted to use real ones, and didn't want nasties leeching out.. Why did you Dis Assemble the Rain system (Just curious), seemed like a good idea. But then again, simple is better I guess.. Like I said Bill, you have inpired me. I will post my build, and thanks again for a wonderful post, very well explained and detailed direction for an over the top vivarium build. Pointing out the importance of water flow underneath, filtration, and access to parts for repairs.. All very important.
