Aquascape Black Silicone Sealant, Safe for Fish, 10.1-ounce |29186

Couldn't find any aquarium silicone in my city, so good ol faithful amazon had my back. Arrived VERY QUICK and brand new condition. Used it for an older aquarium, never done this before but took the leap of faith.Has a strong vinegar smell but goes away completely once it cures. It cures pretty quick so get it applied evenly and bam brand new aquarium. No leaks at all. Awesome stuff!

Purchased a used 40G reef tank a while ago and found out there were quite a few deep scratches on the inside front panel after cleaning it up. Ouch! So I figure since I already ran out budget, I better search ways to save this tank. After reading online forums and articles, lots of mixed feedbacks about replacing/resealing tank panel, I thought to give this sealant a try.Bought this Sealant after reading Amazon reviews. I replaced front panel of my reef tank and resealed all edges and corners. Did a water testing, no leaks overnight, then I filled the tank with salt water! So far the aquarium has been up and running for about a month with no issue. My aquarium looks nice and new with high quality glass front panel. It's not an easy job, but it definitely saved lots of money from possibly having to buy another aquarium! I don't know how much water pressure this can hold, but for my 40G so far it holds really well.If anyone wants to try it, I would recommend watching youtube video and make sure you are working in an area with good air ventilation. The vinegar smell could be very irritating. Also, make sure that you have plenty of time to practice before doing the actual work. Do not go back to where you apply sealant already. Make sure there's enough sealant coming out, so you don't run out of time when applying, and that there's no air bubble in between. They cannot be reapplied in same area because wet sealant does not stick together with ones that are dried already. FYI.

Ido not leave reviews often but this product worked great. Had to patch a large rip in our pond liner. This product came in clutch along with seam tape and extra pond liner. I didn't find that is had a horrible smell. Highly recommend.

Resealed my 300g tank with this. Tacks up quickly so you don't have a lot of working time, but sticks great and has a nice shiny finish when dried.This is my go to for silicone now since GE Silicone 1 window and door now has mould inhibitors in it

I used it to reseal around the skimmer return opening of a backyard pond. Other silicone products were less expensive but I was uncertain of their effectiveness under water. Since this was an Aquascape product I felt that it had been tested and would work. I just finished the project. We will see.
