Heavy-Duty Adhesion
Selsil's aquarium silicone is a one-component, moisture-curing, acetoxy-based silicone. It offers a stronger grip on glass with excellent adhesive properties and durability. Our transparent sealant is also resistant to temperature changes and will not crack, pull, or discolor at high or low temperatures.
For Various Non-Porous Surfaces
Selsil's clear sealant aquarium silicone is a solvent-free alternative to the traditional silicone adhesive. Our premium aquarium sealant adheres well to acetoxy system curing glass and many non-porous surfaces, including aluminum, glazed ceramic tiles, and glass.
Highly Elastic and Flexible
This aquarium glue has high elasticity and a quick curing time (just a few hours). You may use it for repairing leaks, stopping leaks, sealing seams, securing decorations in the aquarium, and other applications as long as the surface is non-porous.

The Aquarium Sealant You Can Rely On
Selsil's high elasticity silicone sealant is an adhesive putty that offers a quality bond to many surfaces. Only a few hours are needed for the aquarium silicone to cure after you apply it to the areas you need to work with. However, if you want it to cure fully, waiting up to 24 hours is ideal. The suggested application temperature where you can apply our aquarium sealant ranges from 41.0 °F to 104 °F, or between 5 °C and 40 °C.

Hope it holds up for use with the Rubbermaid stock tanks. Other sealers got too hard and leaked. May just go with regular pipe dope with teflon if this doesn't work well.

This was my first adventure with a leaking tank. After watching videos and learning what to do, I prepped my tank. Holy moly it's a lot of work to capture the fish, move them to a holding tank, fully empty the leaking tank, strip off the old silicone, and clean and prep everything.Once I got to that point, putting on the SELSIL silicone sealant was a snap. It's messy for someone inexperienced like myself but I got through it. I let the sealant cure for two days. I then filled it with tap water to let it sit for almost a week. I wanted some confidence before I put everything back.Confidence now gained, I drained the tank, and reset it up with the fish from my holding tank. I'm happy to report that I have no leaks, and it looks like I have a brand new tank.The fish are all happy and all quite alive. Approximately 20 cichlids.My only tip, outside of watching some videos, is to be sure to get more than you think you need. You don't want to run out or you'll have to start over. This two pack helped with that.

I was happy to get something that is specifically designed for aquariums. Looked and smelled as expected for an aquarium sealer (which is one way to tell if you bought the wrong stuff). I really like the nozzle that comes with it too. The price was in the ballpark of other sealers, but this one specifically said that it was safe for fish. I have just used it so I can't address it's long term durability, but I am expecting it to do just fine.

I used the SELSIL Aquarium Silicone Sealant Clear to repair a cracked toilet tank (shhh, don’t tell the landlord!), and it worked like a charm! The sealant created a strong, watertight bond that’s holding up perfectly under daily use.The item shipped quickly and arrived in perfect condition, which was a huge relief since I needed it for an urgent fix. The application process was straightforward, and while there is a strong odor initially, it fades after a couple of days.This sealant is a lifesaver for tricky, high-stakes repairs like mine. If it can handle a toilet tank repair, it can probably handle just about anything! Highly recommend this product for anyone needing a reliable, waterproof sealant. Just be sure to ventilate the area when applying.

This sealant worked very well to reseal my 75-gallon aquarium that started leaking out of the bottom seal. I made sure that all the old sealant was removed, and the glass was clean. It's important to clamp it while it is sealing. I let it cure for 48 hours after applying the sealant and slowly filled with water to ensure that the aquarium didn't leak. It is now over 3 months, and the aquarium has not started leaking.
