### ⭐⭐⭐⭐⭐ Nice aquarium sealant
*by W***N on January 24, 2019*

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.
