it is good stuff. I use it to reseal a hot tub but out of the three tubes I got one tube came used open damaged blown apart. It wasn’t even returnable.

I used it to make a fish tank and the bond is good. I definitely recommend it.

Nice, thick, and cures more dense than cheap stuff from Lowe's

It took me a while to find this caulk. It was recommended by various aquarium restorers. Produces a great finished product. a joy to use.

I purchased a large aquarium a couple years back that needed to be re-caulked. After a bit of research I found out that this is the proper stuff. Had to reseal the tank twice because I didn't know what I was doing the first time and messed it up, but 2 years later and the tank hasn't leaked at all, nor have I had any issues with health of my plants or fish. Keep in mind that this gives off lots of fumes when using it, so wear a respirator or use outside. If you're using it with an aquarium I'd reccomend letting it cure for at least a week or two before filling with water.

Resealed a 75 gallon tank with this. IT WORKED! My old tank started leaking in the middle of the night. Woke up and stepped in a puddle! I put fish in a rubber made bin, for a few days (with daily pain in the a** water changes,) scraped old sealant off leaking tank with a razor knife, ordered this and followed a YouTube video for application. It has held up now for 2 months! Great for do it yourself tank repairs. I’m so relieved that it worked. First time doing this. If I can do it you can too. EASY PEASY!

I read up a lot on various choices of silicone for resealing an old aquarium. On the reef tank fourms you hear a lot of positive experiences with this product. Don't be scared of the disclaimer on the tube for not using for underwater applications, this is what the pros use when building sumps and custom tanks. This product skins over very quickly (less than ten minutes) However one should wait 7 days to make sure it's cured before filling the tank. It did a great job on my 75 gallon re-seal project, and she's watertight. Highly recommended!UPDATE: It's been nearly a year since this project was finished, no problems what so ever. I would not hesitate to use this product again should I need to reseal another tank. Side note: I also used this product to install a faux rock background to the inside of the tank's glass and let that dry 7 days before filling. That too turned out great!

Silicon worked perfect. We resealed our 150 gallon aquarium and the (original) silicon between the glass panes stripped and the only thing that held our tank together was the new silicon (this one). Highly recommend
