Aquascape Black Silicone Sealant – Fish-Safe Waterproof Silicone for Ponds, Aquariums, Terrariums, and Home Repairs, 4.7 oz Tube, 22010

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.

I'm no stranger to aquarium sealant or using silicone on tanks. My first impression of this sealant was AWESOME. It is hard to get out of the tube. I kept making the hole bigger and bigger but it's just really thick compared to the usual clear sealant. I'm assuming that is due to the black coloring. No big deal. I was sealing the outside of a leaky acrylic frog tank. The overall smell of the sealant is no worse then the regular clear aquarium stuff. Honestly, I think it smells LESS then the clear stuff! Besides being slow to come out of the tube it was going on VERY smooth. About 1/2 way around my tank I'm thinking just how great this looks and .... BAM You have to put so much pressure to get it to come OUT of the tube that it busted the bottom of the tub clean open. Leaving a blobby mess. Now I'm not sure what to do as I have a huge blob of sealant hanging out the bottom so I decided to start trying to layer that around the bottom of my tank rather then waste it. That's when things just got messy. Be warned this sealant dries FASTER then the clear stuff. By the time I got the blob layered around the rest of my tank it was starting to dry and get grainy. At this point it was the best I could do with the disaster. Now I have 2 more tanks to do and I haven't decided if it's worth using the black stuff or just switching to the clear. It does look nicer on the black bottom rim so maybe I'll order another tube and try again.

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

Works

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

Way better deal to buy a tube this size. We got this big tube for the same price the pet store was selling a little tube.. This was our first time using a black silicone. It looks great, but next time will be a little more careful with our lines as they are more noticeable than clear silicone. We allowed the silicone to cure for a week before filling with water and adding our fish back in.

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.
