Since when do you have that tank and still no leaks ?well I did saltwater so my filtration will be different. (a pair of corallife skimmers, 5gal of bioballs, and 40 gallon sump)
Pond shield was pretty easy to work with, its like very thick paint.
Since when do you have that tank and still no leaks ?

i was thinking to go only with a canister filter finally, is there advantages to a overflow system like you besides a canister?I've been working on a plywood tank myself and I decided to build an overflow bulkhead into the tank with a pump at the bottom forcing water back into the tank. All the media and pump will be contained in the overflow. Haven't finished it yet but it might be an idea for your filtration. Mine is only 130 gallon. This picture kind of shows it.
