Review: I'd say it's worth it, compared to others - Works WONDERS!!! used it for my bearded dragon's tank, sticking well to the wood, glass and various rocks.👍 the tube didn't bust for me (I was very gentle) the smell was expected but not as bad as the comments bad it out to be but that's just me. I ended up having to remove some of the rocks and let me tell you! this silicone is worth it, like seriously it was flexible, but it stayed put.
Review: Works well - Used this to repair a water fountain and it worked perfectly, dried clear and is completely inconspicuous.

## Questions & Answers

**Q: Can I use this to put a rock background on the inside of aquarium?**
A: 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.

**Q: To ensure I am ordering the correct one - this is the clear silicone, correct?**
A: 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.

**Q: Will this fix a water fountain?**
A: Hi there! Thanks for your question. This has not been tested on water fountains, so unfortunately, we cannot advise.

**Q: 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**
A: 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.

### ⭐⭐⭐⭐⭐ Repaired aquarium cracks
*by Y***O on May 13, 2026*

I bought this specific product because I didn’t want to mess with a tubes that require a gun. A few days ago I bought a used fish tank and failed to inspect it thoroughly. Later, I found a couple of cracks in its glass. The cracks were hair-thin and long, not through-and-through. I put strips of masking tape around the cracks, applied the silicone direct from the tube (I did not use the provided nozzle attachment), smoothed silicone with an old credit card, and left it overnight. Next day, I removed the masking tape and scraped extra silicone off with a razor (I keep a surplus of them to score bread). The treated cracks are indeed invisible. I am happy with the product.
