Aqueon Aquarium Silicone Sealant Clear, 3 Ounces | Waterproof silicone sealant, 100% silicone for freshwater or saltwater tanks; permanently flexible, aquarium sealant clear

Bought this product to seal my aquarium which started to leak.... you know.... after 20+ years... Aquarium was drained, cleaned, and dried. These are necessary steps, no way around it. Silicone was applied to clean surfaces. Everything works so far, almost a year later. Good product, practically invisible.

It seals really well, easily spreads and dries pretty quickly. I also used it to cement the light strip to the aquarium hood because it fell off into the aquarium. And I found another use for it because I used it to cement the metal wing back onto my metal crane lawn ornament.

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.

Works as expected..the tube is kind of terrible though and doesnt seem to be actually sealed on the end, because both tubes I have used end up squirting out the back if you dont make sure to squeeze the silicone from the back of the tube.

Very effective sealant. It’s waterproof, and its appearance is semi clear and rubbery when dry. Thickness depends on application process. Easy to apply.

I use this to seal custom fixtures in my hamster cage because it’s nontoxic if she choose on it and it held up way better than I thought it would it also cured very quickly. I will say that it does have a very strong smell so make sure you have a good ventilation, but overall very sturdy and easy to work with.

Great stuff works good. Would be great if you could get a 5-7" nozzle to reach tight spots. Silicone seals Good

Good value for money works great high odor very versatile very effective sealant for my aquarium

Great Product. My main tank cracked half way down and I needed a temporary solution to keep my fish alive whilst waiting for my new tank. I applied the solution onto the crack and it was able to significantly stop the water leaking.

not useful, it is the same material used in other silicon sealants. not worth to buy. go for cheap one.

Used this to fixed my acrylic filter intake tube that I had accidentally snapped. Works great and is a strong seal. Good product... Just be sure you don't get it on your hands like I did, as it's a pain to get off!
