So I made some decent progress on my viv the past few weeks. I mounted the 4 T8 flouresents, the fans and finished the trim work. Last night I mocked up the big infrastructure with cardboard. I will post pictures tonight.

One question I have is about coating the wood. I have 3 heavy coats of polyurathane on all the surfaces and planned on silicone for all the corners. I was also going to line the whole thing in pond liner just to make sure. Do you think that is enough? Would it be a good idea to put some heavier epoxy coating like maybe the fiberglass epoxy type??

Another question...drainage layer...I was thinking of using an epiweb type product...any recommended epiweb like products out there? I'll neet about 3 square feet by 1" think.
