Great for fish tanks and making caves,
Verified Purchase(What is this?)
I didn't seal a fish tank with this - I made a cave. Well, two caves, three walls and an 'artistic structure' to be exact.
It works well, sticks shale together perfectly, and once you have recovdered from the pong (OPEN WINDOWS WHEN USING THIS PRODUCT) you can plop it in your fish tank and watch your little fishies enjoy their new and improved surroundings!
