Aquarium Silicone Sealant (2 x 10.4 fl oz) Safe for Fish (2 Pack)

This is a great product it bonds really good and doesn’t come apart. I use it for all my aquarium needs when resealing tanks, overflow boxes, and adding baffles in my sumps.

Works great for resealing my aquarium.

It’s actually really good silicone. I Re-seal, Re-build, or completely build tanks on a daily basis and I would recommend this brand. Every brand has a drawback or advantage of some sort. The only thing about this silicone I do not like is dry time if you have any thick applications. Allow a day and a half for a basic caulk and inner seal job. If you are doing a Re-seal or complete build where the application is thick going under and between plus the inner seal I would highly suggest 4-5 days for it to completely dry through out. It has a tight, solid, bond with clean glass and is not easily removed once dry..... glass has to be clean and oil free so don’t forget to clean it with acatone just before you apply the silicone.

Used this to make a waterproof foam background for my ball python when he was a baby, worked great and had no issues, very happy with it!!

This silicone is designed for aquarium..It is safe for the fishes.. Silicon dried in 24 hours.. The aquarium would be good for another 5-10 years. (until the silicon lead water)..

I caulked shower, very often in water contact, looks like really truth was vendor selling. I recommend this

Like others have said wear a respirator when applying. Used it to reseal a 72 gallon bowfront I got for free do to it leaking. I let it dry for 5 days and it has been holding water fine for a few weeks now. The key to getting a good result is the prep work you do before you apply it.

To get good use out of this stuff, make sure you do your prep right. We did not, even though we thought we did. So we had put lots and lots of goop on the thin layer of dirt on some rocks and not on the rocks, so the seal did not prevent water leakage. Now user error aside, this stuff STINKS. Stinks so strongly. Its been a few days since applying it and the smell in that room is still bad. Itll make your eyes burn up close.

Good for the money

75 gallon fish tank worked very well
