Works well for snake enclosure.

Worked fine for my ball python enclosure -- even as a first time user. Though I definitely needed a respirator for the fumes burning my throat and eyes, even with a fan on. Took about 2-3 days to cure and I waited a week before adding the snake just to be safe.

Safe for aquariums

I am pleased with the end result. I tape off my corner seams for crisp lines visible when set up. I raise Discus fish. I can't tell the difference between this and clear silicone off the shelf but decided not to risk it and chose this one. True silicone sealant is messy so have disposable rags handy.

Great sealer for aquariums!

This sealer was excellent! It's fresh and did a good job resealing my 50+ year old aquarium. Shipping was quick and came in perfect condition. A+++ seller. Thank you!!

Used On My Boat

I decommissioned the drain hole from my live well on my aluminum bass boat which is on my transom under the boat’s waterline. I started the job by roughing up the outside of drain hole with 120 sandpaper and then wiping area with a damp cloth. I next took a 2” x 3” piece of aluminum sheet metal drilled two corresponding holes through sheet metal and boat’s transom. I next liberally applied Clear Aquarium Silicone to sheet metal piece and placed over former drain hole. I next coated the ends of 2 rivets with silicone and placed them through my pre drilled sheet metal holes and through my pre drilled transom holes. I rivited the rivets with my rivet gun and some of the silicone oozed out from under my sheet metal piece. Finally with my finger I wiped the silicone around the circumference of sheet metal to create a sealing bead edge. The combination of silicone and the riveted sheet metal patch is sturdy and impervious to any incoming water. The sheet metal patch is going nowhere primarily because of the rivets but also the silicone won’t budge unless I apply hundreds of pounds of pressure with a snub nose pliers. Believe me it’s securely attached.

Perfect for my custom terrarium

I converted my horazontal terrarium to a vertical terrarium. This worked well, and I highly recommend it to others.

Perfect for Aquariums

This silicone is very easy to use and doesn't harm your fish. Just let it sit for atleast 24 hours to fully cure before filling the tanks. I use this on ALL of my aquariums.

Works well.

Great adhesion and cleanup was simple. Sealed the acrylic tank it was used on well, no leaks with a thin bead over the already solvent welded joints.
