will this be safe for fish?

  • We are currently upgrading MFK. thanks! -neo
That's a tough one man. There's no stating how well it will work on wood. you may need a primer? not sure. It says concrete on the page, it may adhere to concrete board.

I'd say build a quick 10 or 20 gal ply and test it out with water for a while until your ready to use the product in your big plywood tank.

Being human safe I think it would be okay, although I would probably fill the tank let it sit for a week, no leaks, good, drain it, refill. This will help rid of any toxin's there could be...
 
that sounds like a pretty good idea
 
Not sure about that particular brand but I do know "marine paint" isn't neccessarily safe for fish. It just means it won't flake or peel underwater.
It's probably not an option for you but a lot of people use Krylon Fusion spray paint. I don't know how permanent it is though.
 
i have used it on PVC but i noticed after being fully submerged for about 1 ear its very brittle. On the other hand the stuff from lowes is a 2part epoxy and is safe for our pools.....
 
Something that has been deemed safe for humans shouldn't be assumed to be safe for fish. Filling and emptying the tank may not work if any toxins slowly leech out into the water. I would be on the safe side and stick to a product approved for ponds.

the problem is the cost... im sure there are a ton of stuff out there we COULD use that is much much less then the "fish safe" but we dont know if its safe or not ..

i would say .. build a small tank .. use it .. toss some feeders in it .. and see what happens .. as soon as you feel you have done enough testing use it in a tank that has fish you REALLY care about. i am doing the same thing with an acrylic paint as we speak.
 
well i didnt read all of it but the msds claims tons of toxic chemicals. I would assume all of them will kill fish but i assume they are refering to wet paint it may have a different chemical reaction full on dry i agree make a ten gallon ply tank paint it fill it wait a week do a 100 percent water change fill it again wait a week and introduce a healthy looking feeder goldfish it might work at that price it couldnt hurt to try a test and a feeder golfish is cheap and destined to die i would also question them about the way the paint bonds to silicone it may break down in a short period of time
 
the gallon can says non toxic once cured on it. And I wasn't assuming anything, thats why im here asking. Ive seen one guy use dry lok and so far its been working great for about 6 months.. so thats another option
 
about the epoxy it seems that going too cheap would be a bad idea.

see this article. http://www.jonolavsakvarium.com/eng_diy/2200litre/2200litres.html

also read this on the strength issue.

it seems that anything that would scar/puncture wood would cause an issue. this would include any rocks or driftwood you put in the tank and remember some fish are known to ram the sides like red belly pacus and piranhas.

the more and more I read on the plywood builds, the more I would design it like a shower. using a wood frame, backer board and then tile with the sealant/epoxy. probabally heavy as hell but durable and would look nice.
