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

I used this product primarily for the fact it does not have any bacteria, mould resisting properties included in its composition. The reason being I required a product without those qualities for a sump I had put together for a marine fish tank. Some silicon sealants cure too slowly this one however did not, from application to curing took initially about 5 minutes. At this point the Silicon held the glass panels in place. I also noticed that there was no bubbles forming in the silicon, and the silicon was clear in colour without any yellow tinge.I have since tested the silicon for its ability to hold and seal when filling my sump up with water 48 hours later and can confirm that it holds steadfast and does not leak. I would recommend this product to anyone planning on carrying out work involving an aquarium or pond.

Used to seal a vivarium. Used previously on other projects durable non cracking. Permanent water proof seals non toxic to reptiles ( never affected our bearded dragons) quality product and a good value

One tube slip leaking silicone everywhere 1st tube was brilliant second tube must of been faluty

The main feature required was that it was "pond safe" I have a raised pond in which I needed to control max level. This product seemed ideal, and at the moment is doing the job as well as I could wish for. Tomr

I wanted to seal a couple of areas that were letting in water. I never had a lot of luck with marine sealants as they always breakdown after a while and go powdery. So I thought I would give this aquarium sealant a go. If it works in seawater it must be good. Well this stuff is amazing. No more leaks (which is always good on a boat) and easy to apply. The best bit it’s flexible and quarter of the price.

Very good so far. Used to sure up a tank and also to bind a false bottom. It does it's job well and very good value

Not all that great a product does not cure well. Peels off easily

Used to put together a 3' x 18" 6mm thick glass display cabinet, left overnight to cure and very solid in the morning, I'd recomend using a silicone tool (such as the fugi set) to get accurate strong uniform joints
