Works and does wonders

I've got a large KAGES snake terrarium that I internally sealed with DAP aquarium silicone when I first put it together. Unfortunately, on top of the DAP silicone being a pain to apply because most tubes where partially dried out from sitting on the shelf and having to be squeezed by hand, the terrarium started to leak if enough water pooled; which means that the plants and springtails haven't been able to thrive like they did when the setup was a glass tank. Took a chance on this silicone sealant to apply to the outside of the terrarium in hopes that it would solve the leaking problem, and thankfully it 100% has. It's now holding enough water that all the plants that were on the verge of death, are now perked up and happy and the ground cover is finally looking like it's gonna spread like it's supposed to. Definitely a better choice than the DAP sealant.

I used it to seal around the filter box of an exterior koi pond and it was easy to use and looks great.

Smells very strongly of salt and vinegar chips. It’s also a pain to open. I had to look up a video on how to open this thing and needed to take a knife to it which is dangerous. Other than that, using a cheap caulk gun from Walmart, I was able to get my project done. The applicator is great for allowing small to large beads of caulk. Seals very well and seems to adhere to several kinds of materials pretty well.

So my brother gave me a 39 gallon or so bowflex. Come to find out it leaks very slowly. So bought this pickle vinegar smelling silicone. Resealed over the old silicone. Made the bead much larger. 24 hours later filled it up with water. So far no leaks at all. Yes it will burn your eyes if u are face deep in the tank applying it. Scraped off the excess with a razor blade. Overall not bad worked as intended. Smell is abit overpowering when it's curing.

The tubs com with caps

I only got one tube. Where is my second tube of the sealant? I would like another one sent because this is not right that I was missing one.

My old tank is over twenty years old with a metal bottom framework and started leaking. I went to buy a new one and saw how cheaply they were made so I said let's just try to fix it. I completely took the old silicone off and replaced it with new. I had to do it in stages so the aquarium would not fall apart. After about three stages and five days (had to let it cure} I nervously filled it up. NO LEAKS so far and it's been over three weeks. I saved over 150 bucks and have a better tank than you can buy for that.
