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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Que fue muy útil *by A***L on 17 February 2026* Me ayudó con la fuga de la fuente de agua de mi mínima ### ⭐⭐⭐⭐⭐ Great product. *by J***K on 10 April 2019* This is a great product. I sealed a 110 gallon tank with no problems. The one thing I disliked was it was really difficult to squeeze it out using a caulking gun. ### ⭐⭐⭐⭐⭐ Awesome gasket for my butter dish *by M***L on 1 September 2019* I have a butter dish with a lid that I absolutely love, however once summer came small gnats were coming through the open screen window and getting through the gaps between the lid and dish itself and into my butter. Yuck! I decided to make a gasket so the lid sinks into position and seals so nothing can get in. Worked out awesome! Super happy. Figured if its safe for fish its safe for me. ## Frequently Bought Together - Aqueon Silicone Sealant Clear 3 Ounces - Fluval 12694 Plant and Shrimp Stratum for Freshwater Fish Tanks, 8.8 lbs. – Aquarium Substrate for Strong Plant Growth, Supports Neutral to Slightly Acidic pH - Aquarium Glue, Clear Reef Adhesive for Plants and Rocks, Moss, Coral, Stone, Wood, Plant, Suitable for Freshwater and Saltwater Aquascape, 5g*2pcs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/260202675-silicone-sealant-clear-3-ounces-waterproof-silicone-sealant-100-silicone](https://www.desertcart.us/products/260202675-silicone-sealant-clear-3-ounces-waterproof-silicone-sealant-100-silicone) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-15*
