Black Aquarium Silicone Sealant is a 10.2 fl oz high modulus RTV silicone designed specifically for fresh and saltwater aquariums. It bonds strongly to glass without primers, cures overnight, and remains clear without yellowing, ensuring a safe, durable, and visually clean seal for your aquatic projects. ## Description ASI Aquarium Silicone Sealant has been specifically formulated for the fabrication of fresh and salt-water aquariums This high modulus component RTV Silicone Sealant forms strong cohesive bonds to glass without the need of primers Review: I used this when reconditioning my 2006 50 gal aquarium, which has now been setup for a year after application. I used the clear, it's none yellowing and it's still mostly clear. It's actually mostly opaque in the thicker areas and clear in the thinner feathered out areas. It's easy to apply, well maybe not as easy inside of an aquarium, you need to move quickly and not touch the same areas twice. You may also need some paint thinner or similar solvent based thinner to clean up any mess. It's best to just let it dry, and use a new razor blade to scrape any excess off. Just make sure everything is prepped and very clean prior to application. One tube was plenty for the tank, I used 1" blue tape helping with straight lines. It's not necessary, but it does help make things look better. Cures overnight, but I gave it a few days prior to my leak test. They also have black, but I like the clear better on this tank. I'm sure it would be a great silicone for other applications, so use it up before any remaining in an unopened tube cures inside the tube. It's good stuff and well worth the money and your labor! Cheers!

In other words, it'll work just fine. **Q: I placed travertine in my aquarium. Will thus seal it so water will not get under?** A: As long as the material You are putting in the aquarium is NOT porous and you make sure any openings are closed up this should work for you. Of course how much you use and the depth of your aquarium are factors as well as if you don’t apply enough and if one has a big tank the pressure on the seal could brake. I use this to make retaining walls for landscaping my aquariums and its been working great for me. **Q: Will this adhere to cured silicone. I have a spot that seems to be cosmetic and would like to add more.** A: It will - but it wouldn't be effective. I would scrape off the bad section and apply the new silicone. **Q: could this seal pvc to abs plastic?** A: Yes it will. The silicone will adhere clean smooth surfaces. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***R on 4 August 2024* I used this when reconditioning my 2006 50 gal aquarium, which has now been setup for a year after application.

I don't buy it for anything but aquariums, because it is more expensive -- but I won't ever go back to the cheaper product. You can feel the difference when you put it on -- even with clumsy old hands like mine. You can trust the seams not to leak if you have done a proper prep job. If you are ever trying to dismantle an aquarium, you will find this product holds much, much tighter. I've broken glass trying to take aquariums apart after using this product so if you are after a temporary fix this is not the one. But if you want something permanent, this is your product. I've used both the clear and the black and highly recommend them both. I've operated an aquarium store with many custom made aquariums that were assembled using this product and never had one leak, even when shelving over time went out of level, adding a great deal of stress to at least one corner of a few aquariums. ## Frequently Bought Together - Black Aquarium Silicone Sealant - 10.2 Fluid oz Cartridge - GREAT STUFF 99112849 Smart Dispenser Pond & Stone, 12 oz, Black - Clear Aquarium Silicone Sealant - 10.2 Fluid oz Cartridge --- ## 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.vn/products/259861725-black-aquarium-silicone-sealant-10-2-fluid-oz-cartridge](https://www.desertcart.vn/products/259861725-black-aquarium-silicone-sealant-10-2-fluid-oz-cartridge) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
