Rated 4.0 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by easy repairs Used this product to modify two separate aquariums. Never leaked and never peeled, did exactly what it said it would do January 14, 2015
Rated 5.0 out of 5.0 by works well, great price Finally I found some aquarium grade silicone glue at a decent price. Works great. I did not want to chance my fish to regular silicone glue. April 13, 2014
Rated 4.0 out of 5.0 by silicone This product sealed great and was easy to use. The only problem I had is the tube was difficult to squeze and seemed to work better if i rolled the bottom of the tube up. October 13, 2010
Rated 4.0 out of 5.0 by Product name Just a note, when I purchased the product it was labled as 'Household' sealant for ceramics and aquarium and NOT 'Aquarium' sealant. Not much different, but it took me extra time to find it. August 16, 2011
Rated 4.0 out of 5.0 by Larger Tube Great stuff, but would be easier to seal a larger tank if the tube was bigger and fit into a caulking gun. December 28, 2010
