I am looking for a water safe glue to use in one of my tanks. It would be to bond rock and PVC. Is there such a thing as water safe glue. I am guessing silicon sealer wouldnt work.
several types all with varying price and effectiveness. personally have always done my gluing outside the aquarium in the dry..then toss it in, but have just made sure its water safe/fish safe...
I have used this with great results; it's strong as steel when it dries and is completely safe. It cost about 3 or 4 bucks at Home Depot. Just follow directions.
Find a local pond store, they cary cans of fish safe black foam. Its called Atlantis Fall Foam bonds anything i used it on my rocks b/c the spill over is black and looks natural if using river rock.
