You have heard it thousands of times, but hows Drylok at sealing tanks? If being applied right to the wood? I remember when everyone was first doing it, well a few people. Any updates? You guys must have some more info on it.

Don't hold it against me. 
I've used dry lock with varying degrees of success. I don't suggest it since the manufacturer won't qualify if for wood. I've seen pin hole (air bubble?)leaks in the paint surface cause major problems. Some people are using backer board (hardy board) inside the main box and sealing that.
I don't know where the others that used this are?! Might have to do a search for the threads & PM them.
Hope they didn't drown when their tanks gave way

i dont know about using either for a tank. i work for lowes and i sell both all the time. hardi board isnt supposed to be submerged all the time. the way its made it would leak imo. it isnt solid. drylock on the other hand would be good but like the doctor said it isnt meant for wood. you can use it against the hardi board though. lol. just make sure you dont have ANY air bubbles in it. they will leak and cause you a lot of problems,
I wouldn't use it. I would just spend the extra bucks and get something that will positively seal it tight. I used Drylock in my basement and thought it was worthless. Gave up about $100 into sealing. Go with and epoxy or fiberglass it.
if you are looking to do something inexpensive and well i found fiberglass resin to be a great sealer but it is not fish safe or completly waterproof paint over it with a drinking water grade marine paint this will make it fish safe and completely waterproof.
Unfortunately i don't know anything about this drylok but what i can tell you is would not ever again try to build a tank without fibergalssing it first and i dont know if drylok would addhere to fiberglass but the paint will better than an epoxy gel.
