Aquascape Black Silicone Sealant – Safe for Fish, Waterproof, Flexible, and Durable Adhesive for Ponds, Water Features, and Aquariums, 10.1 ounces, 29186

Work great i will buy again for sure

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.

I highly recommend this product for sealing seams or gaps in your pond. I used it around a leaky waterfall feature. It went on easily using a caulk gun and remained very flexible once it cured after 30 minutes.

Would rate it 5 but I didn’t like the consistency of this. It is super runny so be prepared for that where other aquarium silicones I have used are a bit stiffer. Needed black though and it worked so a 4 out of 5 for me.

Very good product, the best I've tried thus far.

Como era un frasco pequeño pensé que no iba a hacer un buen trabajo pero realmente pude reparar mi acuario con esto, y e podido reparar otras cosas más así que es multifuncional. Pega muy bien se siente firme y a la misma ves flexible así que no veo riesgos de que se quiebre

I silicone my pond filter. I'm using a 50 gallon plastic drum. Wiped everything down with alcohol first .Worked real good so far

Is as described. Used in a Koy pond that was given to me that had several holes and slices in it. Allow 24 hrs to dry before applying water it helps

used before and great product

Covered all the holes in our pond!

Excellent product! Good adhesion, easy to clean up residue. Sealant flows easily when tip is cut. Product used outdoors.

Used it to seal up a large tank and it’s still holding. I made fat corner beads and let them cure for 4 days, until the beads felt solid. The Black looks better then the clear did forsure.

S applique bien sèche bien parfait
