Sealing a plywood aquarium or sump

[Sacohen]

Does any one know if Flex Seal is safe for sealing plywood aquariums?

I used a rubber based paint that is used on pools. It's used for fresh and saltwater pools. Goes on very thick and helps with vibrations as well. I got it from Home Depot, had to order it on line.

Thanks.
You used this on a tank?
I'm assuming you haven't had any ill side effects like high phosphates and all your stock is alive.

In only used it on the stand. No water is circulating/touching the paint that goes in the tank.

[Sacohen]

Yeah, I want to use it for top off water storage so water that touches it is going to go in the tank.
Gotta look into to this more thorough.

+1 I used the same product to seal the bottom of my stand. You do need to give it time to fully dry and to out gas.

Binford said out gas. :)

I don't know why I didn't notice this before, but if your just using it for top off water honestly its probably going to be cheaper to just use a small glass tank unless you have the plywood laying around extra already as I don't think you use the cheap osb plywood.... atleast the ones I have seen don't.

I didn't have room for a small 10 gallon tank, but I bought one for $15 and sanded the black plastic frame off the sides and it fits perfectly in the space I had.
