Clear Aquarium Silicone Sealant - 10.2 Fluid oz Cartridge

Sealed up my aquarium nice and tight with no leaks. This stuff works. It has a strong smell but works great.

This sealer was excellent! It's fresh and did a good job resealing my 50+ year old aquarium. Shipping was quick and came in perfect condition. A+++ seller. Thank you!!

I am pleased with the end result. I tape off my corner seams for crisp lines visible when set up. I raise Discus fish. I can't tell the difference between this and clear silicone off the shelf but decided not to risk it and chose this one. True silicone sealant is messy so have disposable rags handy.

Worked fine for my ball python enclosure -- even as a first time user. Though I definitely needed a respirator for the fumes burning my throat and eyes, even with a fan on. Took about 2-3 days to cure and I waited a week before adding the snake just to be safe.

Is a quality silicone but read the instructions wrong thinking it had a 24 hour dry but is only 24 hour cure, and has a 7-14 day dry time, which is inconvenient.It has a strong smell which takes breath away and burns your eyes when applied so use in well ventilated area. A sealant tool did not work, you have to use your fingers to smooth the seems, and only have seconds to smooth out.Seal one seam at a time because of the very short set up time and will not be able to go back and smooth the sealant.Applied a masking tape but you must immediately remove the tape, or it will damage the seem causing to remove and reapply, if removing after minutes.Keep the screw on tip installed if you don’t use entire tube.Resealed several aquariums and canister filters.Plus - Did use this sealant for greenhouse polycarbonate panels ILO the clips holds and seals. Allows for easy replacement years later versus the calking (very difficult) and foam which is unsightly.

Great adhesion and cleanup was simple. Sealed the acrylic tank it was used on well, no leaks with a thin bead over the already solvent welded joints.

Perfect adhesion around the drain of a pool, and held together the edges of a fish tank. No leakage, great appearance! Works amazing!

Good stuff, worked as it should and tank is holding water. I used it on a 22 year old 55 bow front that sprung a leak. Followed directions and removed all old silicone. Gleaned glass with acetone and ethanol to remove residues and let it sit a week. Applied the sealant free hand. No need to tape off; that it just making too much work and when it is full of water you will never know. Let it it 10 days to fully cure. No leaks, been together two months now. I could have used a half sized tube and when I was finished I was looking around and thinking what around the house needs to be sealed up? Yes the acetic acid smell is strong so keep your head out of the tank and do outdoors and leave it there for at least a week. It will smell for at least 4 days, even out in the sun. Hopefully it will last another 20 years.
