Most drylok tanks start leaking after about 1 year. and some sooner than that.

Man I hate it when people say things like this without examples, links, or any other kind of explanation to back themselves up. If this is a fact, can you please share with the rest of us what you're basing it on, because you're the first person I've seen say something to this effect. If you're right, it'd be a good thing to know for everyone here.

agree....i'm gonna experiment a similar project but with drylok masonry waterproofer then drylok latex.....hoping the masonry waterproofer will hold to plywood

Hmm,look up drylok aquariums,there are many that are like 1 1/2 years to 2 years. I will post pics in a bit, need to do something.
 
When i stripped the box to look for a leak,i found a hole where a screw used to be,filled it
up,it leaked from these hole and this hole only,filled the hole with a dollop of drylok,gonna fill it up again tomorrow
 
drylock is a masonry paint. A guy on the sister board did this on his 150gal plywood tank and had a leak. Took the tank apart and the paint never stuck to the wood. Drylock isnt for wood
 
Thats odd, many people have done this and it sticks to wood, including myself. I painted 3 coats of drylok on an 12"x1" piece of ply and dipped it in a bucket for a month,took it out then cut it,bone dry. Thatfishguy has a drylok on ply 120g that has been in service about a year. Also know 2 other people who did a 75g and a 90g 3 years ago,no problem at all.

I heard its better if you put it on the rough side of the ply,maybe he put it on the smooth?

This goes for any type of plywood tank really. Fiberglass/epoxy won't stick to wood that's not properly prepared. Polyester resin in particular is prone to peeling off wood if the wood was wet, or chemical treated when it was applied.
