Best Aquarium Grade Silicon!
This is high quality made in Germany aquarium grade silicon (Not all silicon companies state this but this one does) It is a lot thicker than Dowsil and others that I have used in the past which made it difficult to inject it in between the glass panes so I had to return the second one. Even then this is by far the best silicon available in Amazon.in for aquariums. EDIT: Aug 2022. Purchased this again and built a large aquarium using silicon injection method. This time the project was smooth. This is a very high quality "Aquarium grade" silicon. Best available in India for sure. Mind you it is a bit harder to work with as it dries faster and is thicker than the popular Dowsil silicon. Very happy with the results. Will definitely use it again if I ever build another fish tank.

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.”

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.
