Making caves for aquarium, need help ASAP
I bought pvc today to make caves but need to make sure my silicone is the right stuff to glue the rocks on. Got it at Home Depot. It is GE Premium Waterproof Silicone II (for windows, doors, attic, basement) but says it is 100% silicone.
I just recently used the same one about two weeks ago. Just remember to cure it a minimum of 24 hours before you put into the tank.
If the silicone you have purchased has a mold preventative in it, it could be risky. In the link above it says to check the website as some ingredients are listed there that may not be on the container itself.
ACE Hardware also sells Aquarium Silicone.
Sorry, but GE II is not safe as it includes a mold inhibitor additive that will kill everything in the tank.

Thanks everyone. I took the Silicone II back and got Silicone I. I made 2 PVC hides as well as 2 coconut hides.
