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

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.

Easy to use worked perfect

Have a welded plastic Ranchu pond that split a weld this winter. I wiped it down with a wetpaper towel, let it dry and glued is. 48 hours the fish were seimming in it

This is great silicone to work with. It cures very fast and goes a long way.

Good product

I had a sink drain that partially rotted. It was metal. I tried a ton of different ways and 2 other silicones, and pvc glue and reducers to convert it to PVC. The old metal pipe was somehow cemented into the pipe in the wall so replacing the whole thing not an option. This did the trick. Water tight connection.

Very happy with the product

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.

No instructions on curing time, you cant read the writing on the tube, doesnt go on as smooth as some other silicone I have used

This product is an absolute nightmare. It doesnt have any real instructions on it... The pictures showing you to just cut the tip with scissors are hilarious, given that is simply NOT going to happen. Im also not sure why they bother to attach a screw on tip, because you are NEVER going to be able to squeeze this enough to get it to come all the way down the tube. After cutting it who knows how many times (20?) with scissors, I was able to MAYBE squeeze a pea size amount out at a time. I gave up after my 20th little dot because I was so exhausted from trying to squeeze more out that I legit thought I was going to have a heart attack.
