What kind of silicone did you use? Most of the GE 100% silicone caulks I find state "Do not use under the waterline or in aquariums". All the other "aquarium silicone" are horrendously overpriced. I have a feeling it's just the same stuff...

You can get clear or white aquarium silicone at home hardware for like $6.5 a tube. Just picked up 2 yesterday to reseal a 70g.

Nice work.

That's pretty much what I figured - thanks for confirming! I couldn't see how 100% silicone was going to be that different between aquarium grade and non, except maybe what gets released DURING curing...

I would be VERY careful with the white silicone, it usually contains a mold reducing ingredient, poison. I know there is a fish safe silicone, and a range of not safe ones, I would google DIY Joey and watch his recommendations.

i used aqueon silicon but yes...it is ABSOLUTELY OVER PRICED...

PS: the seal failed, the corner was still drippy, just got a new aqueon tank from petco on a visit to the US, the tank was cheaper than the silicone though...how ironic

i mean...the old one was a Tetra tank, and they have bad reviews. also i kinda moved it too much so maybe the glass has loose seals and it was kinda my fault
