Having built a number of large tanks for aquaculture, I can give you some
advice. For starters, I'd use 1/2" acrylic as a minimum for the front. A
piece of glass that size is very awkward to work with. Very awkward. As
Also, rather than sealing the plywood with (expensive) epoxy, consider
building the box and applying a face lamination of thin (cheap) acrylic.
For the size tank you are talking about, $20-30 should cover it.
I use this order of operations: cut plywood to size; assemble box with
glue and screws, finish the outside; cut a piece of thin acrylic to size of
bottom less 1/4" (if the inside measurement of the bottom is 5' x 1', I cut
the acrylic to 4'11 3/4" by 11 3/4"); contact cement the acrylic in place
so there is a 1/8" space all around the bottom; do the same for the back
and ends; cut the front to fit with the same 1/8" gap at bottom and ends
(but the top should run all the way to the top); seal the front in place
following the procedure everyone writes about; seal interior joints.
I use a sealer called "GOOP" for all sealing operations. By actual tests,
I have found it to be aquarium safe and long lasting. With acrylic, I
usually scuff the area to be joined with 400 grit emery cloth (but the
times I've forgotten have worked out fine). I double seal each joint-apply
the sealer so it goes 1/4" on each side of the edge and let it dry, then go
back and do it again 3/8" wide.
Don't forget to tie the top together-for a tank the size you are talking
about, I would use two ties across the top-dividing the top into thirds.
In 1992, I built a huge tank for a friend-2' x 3' x 20'-it runs around a
corner in his basement! He couldn't bear to part with a large catfish. No
leaks so far.
