Good quality
“i build 4 feet height 2 feet lenggt tank. The gum is super strong, but it’s very hard to use. It dries very fast—within about 10 minutes it starts getting hard—but once set, the gum is very strong.”

It is waterproof, meant for aquarium builds
had doubts when i bought it online, but its quality is much better and suited for aquariums unlike the local brands which mention water resistant but not waterproof, no regrets

Best silicon ever in the market, for aquarium.
Great product, dry instantly and very strong bond. My 400L aquarium seems pretty strong with this. Even you can't see any wobble of Glass when pulls or push like other silicon glues. But you need to carefully apply this one. Highly professional. I had used 2 bottle. After that i bought another astral brand silicon one from local shop, then only i realised about the quality of this wacker product, it's 100% greater than any other product in the market. The astral silicon i brought from the shop had a worst smell also it takes more than 24 hrs for dry. And also not having water holding capacity. But this one is great. Only cons i had was they don't sell smaller ones. If i need a 50ml or 100ml i have no choice for choosing this one. Because this product can't be stored for long after the seal broken.
