Very strong bond, cures quickly, and is safe for the aquarium. A single tube was enough for my DIY 55 gallon sump. As others have mentioned, the smell is intense when first applied so be careful. Per the instructions, this stuff will skin in 10 minutes and fully cure in 24hrs.

I used it to help make my own sump, while I didn't use it to seal any outside joints, this stuff sealed my dividers as well as my filter sock section strong and water tight!

Top Notch Silicone By Sirjohn on 1/2/2014
Sirjohn would recommend this product to a friend
Tried other brands and was apprehensive about this but thought I would give it a try...Fantastic, cures quickly, and is very very strong aside from the fact that its black... Much better than any other silicone out there.. I will use nothing else... The smell is intense when you use so make sure your outside in a well ventalated area.. But cures quickly..

I've tried a few other brands of silicone and this is the best I've found. Not to many companies make black silicone and this seems to be the most durable with the highest tensile strength.

It was my first time creating a DIY sump/refugium (heck, first time using a caulking gun!). This stuff was so easy to work with a dries very clean and clear. Obviously I don't have a point of reference for comparison, but I was very happy with this stuff.
