Thanks stempy. The total system volume will exceed 1000 gallons. I will be building 2 similar (hope to go a little longer) plywood tanks to tie in. Until they are built there will be 6 tanks ranging from 30 to 65 gallons tied in, and a 100 gallon Rubbermaid refugium. I will be building a large unlighted cryptic zone with another 100 gallon tub in the future also. I expect it to take a couple years to get all done. Sump will be way oversized until the first big tank is online! Thanks for looking!
Coolkieth, I will be sure to have the whole thing documented here! I did a lot of reading and consulting with successful builders before deciding the pour method was the way I would go. I will have almost 1/4" of epoxy on all surfaces that was applied in 3 layers, I expect the water test to be pretty uneventful, since I didn't even have any epoxy leaks in the first pour. If you look around in my build pictures you will see that I am lucky to have a well equipped shop. The birch ply was an easy choice for me. It's only about 40 bucks a sheet for the cheaper stuff, it's flat, and not full of the voids you speak of. Woodworking and furniture building is my other hobby, so I am excited to be able to mix the two. In fact I hope to possibly sell a few systems someday that are pieces of furniture instead of the run of the mill aquarium projects. Thanks for tagging along!
