I've used it with glass and plastic aquariums. It worked fine for me and shouldn't be adhering to either. As long as you keep the hose in motion you should be fine. I've also used it on sand and it wouldn't suck the sand up with it as long as I paid attention to what I was doing.

Question about All-Glass Silicone Aquarium Sealant.
We have a 45 gallon tank with a very slow leak. Do you if its possible to seal the leak from the outside without having to empty out the water and the fish - with this product? thanks

hi. sealing from the outside will not work...with the water pressure so high in the tank the water will find any tiny hole...I have had tanks in that size with small leaks and all needed to be sealed from the inside.
its a pain to do all that work but if you seal it correctly its cheaper then having to replace .
