Can I use this to put a rock background on the inside of aquarium?

Absolutely. I bought it to make an aquarium into a vivarium (1/2 water and 1/2 land). Works great. If you are using lots of small rocks, lay it on its back and spread sealant with something disposable like cardboard or a wood shim. Dont be shy. Use a lot. Press rocks in and let it dry good (48 hrs). When you tip it back up a few might fall off, more sealant and patch it in. I find smaller rocks work better than larger.

To ensure I am ordering the correct one - this is the clear silicone, correct?

yes it is clear, nice size tube, I glued my hole ten gallon aquarium and have enough left to fix several more,I though it was a good buy when I looked at the price at the store and I didn't have to hunt for it.

Will this fix a water fountain?

Hi there! Thanks for your question. This has not been tested on water fountains, so unfortunately, we cannot advise.

What tool did you use to squeeze the tube? It takes alot of pressure to get it to come out and i can only get about a foot done at a time

Hi there! You shouldn't need a tool, but it is possible that the product has expired. We kindly advise you to contact us at 1-888-255-4527 so we can send you a new tube.
