2x Bond It Black HA6 RTV Silicone Sealant Marine Aquarium Safe Water Fish Tank

Good product I bought wrong colour though so had to return and re purchase

Easy to use and works well in a vivarium background

Does what it says on the tin! cheaper than some of the premium name brands..

Purchased this to repair a couple of old large glass aquariums I had sitting around. I first checked what was available at my local fish stores however I was disappointed by the selection; all they seemed to stock were small stingy tubes of silicone costing about twice the price of what both of these good sized tubes cost.Soon as the silicone arrived I got straight to work. One of the tanks has completely knackered seals, I used this to repair both the inner tank seal, and the seal between the panes of glass. After applying this and letting the silicone set for a few days I filled the tank up, and got my fish + shrimp in there! So far, no leaks whatsoever, the seals look perfect and no deaths from the fish or sensitive shrimp so I'm certain this silicone isn't leeching any nasties into the water.Overall, an excellent buy if you're looking to repair an old tank or if you're looking to build your own!

it is a very good item great for using indoor or out fish safe and great for extreme weather

Good

Really quickly to dry. I have the water and fish back in the tank 12+hrs and so far so good! Great value for money

I've used this indoors for background setting I used Cork and it sets quite quickly. I've used it outside too great
