water proofing plywood ?

  • We are currently upgrading MFK. thanks! -neo
Remember there is before cured and after cured, that is most likely in its uncured state. But why even bother with something potentially risky to your fish and not use something proven to work?
even the proven methods had a trial stage.
 
I say try it.

There's 3 really big cinder block tanks at my local 4h grounds. They sealed them with rhyno liner (essentially the same thing) and have had them stocked with native large mouth bass and walleye for years.

I think there's a lot of promise in this.

And like was said before, the warnings are likely in the non-cured state. Once cured, I don't see this stuff leaching much.
 
I say try it out on a small tank and try it out on some feeders for a while. Just monitor the little guys and parameters and see what happens. I wouldnt try something like that on my stock but on feeders, why not?
 
Has any one used this stuff for water proofing your plywood tanks?

And few of the spray on truck bed liners have been used in fish ponds and plywood tanks. I don't recall if Herculiner was one of them. As I recall the two-part spray on types ended up being very expensive and silicone doesn't stick to them. Personally I don't think the latter is a huge problem as there are ways around it. The cost may be worth it if the speed and simplicity of having somebody else spray it on is worth the money to you.

But if you're in that price range already I would strongly encourage you to look into having somebody spray polyurea on for you. The poster Pacu Mom (or something like that) has posted some links re. polyurea recently. Same issues with the glass but probably one of the better products for sealing plywood or concrete aquaria.

Don't use it on feeders you intend to feed though. If chemical residues are getting into their water and are fat soluble, they'll be stored and concentrated in the fatty tissues of the feeders.

Also, if you use feeders, make sure they are the rosy minnows. Fat head minnows are a little more sensitive than goldfish.

you here this with several product that people have used. If I had this problem I would use the plastic clips that screw on walls to hold mirrors on the wall. and just seal up the clips with silicone.
