Review: Works great on metal framed vintage aquariums. - I wanted to use this silicone sealant on my vintage metal framed fish tank. Easy to use and work with. Once cured there have been no leaks.
Review: Saves My Pond! - I use this seasonally for a bit of an unconventional use: sealing the lid on my biological pond filter to make sure it stays completely airtight. I have a homebrew system made out of a five-gallon bucket with a solar-powered 12v pump inside that pipes the water out to a waterfall cascade. Water is drawn into the bucket purely because of the suction this creates inside the hard, rigid walls of the bucket, so for this to work that means the bucket has to be perfectly airtight. The silicone aquarium sealant works -perfectly- for this. I put a small bead around the edge of the screw-on lid (the kind they make for storing grain and pantry goods in such buckets) and when I engage the pump it pulls the sealant slightly down into the threads good and tight. The key is to only screw the lid on until it is barely tight, not very tight. When I want to open up the filter, I simply pull off the sealant from the edges, unscrew the lid, and apply it again when I am ready to close it. It does mean I go through a fair amount of sealant on a yearly basis but it's 100% pure peace of mind knowing that it'll keep our little family pond clean and easy to maintain without having to shell out the many hundreds of dollars for fancy canisters with specialized pumps and filters. One thing to note is that you -do- want gloves on to apply this, but it's not a completely loss if you get some on your skin. This sealant does not burn. I found out to my dismay that the pet store sealant BURNS if you accidentally get some on your skin. This stuff is just a pain to wash off. It is actually easier to get off skin if you let it dry and peel it off afterwards. I have -not- found a way to get it out of my clothing at all once it dries, so don't get it on clothes! My only qualm with this particular sealant is that the price does seem to fluctuate quite a bit. Sometimes getting the three-packs from other listings on desertcart is a better price overall. Still, very much recommended!

## Questions & Answers

**Q: Can this be used to fix a fountain in a reptile terrarium**
A: Yes, but keep in mind everything has to be completely clean and dry before applying it. Also keep in mind it is a sealer, not an adhesive, so it won't hold broken pieces together.

**Q: I have a crack in the glass on the bottom of my tank. Will this seal it?**
A: If tank has a frame beneath it's tricky. The silicone will seal it providing you prep the contact area. You must clean away the old sealant & calcium buildup;this is for outside & inside the tank.
It requires a one inch bead on both sides of the glass, *then two inches onto the old silicone - both sides of the crack. Mash/feather new sealant beyond each side of old seal.*

**Q: Can I use this to fix leaks in a horse trough around the heating element? Will it hold it's integrity against freezing temperatures?**
A: It should. Just make sure all surfaces are thoroughly cleaned and dried before application. Silicone can withstand sub-freezing temperatures and very high heat. After application you should wait 1 week before using the trough though.

**Q: Can I use this to bond glass with acrylic for the overflow to my tank?**
A: You sure can, I use it for that very same purpose.
