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

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.

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

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.

Good stuff, a little messy though

Perfect

This was a simple/effective solution I needed for a hole in our large-ish (former koi) pond liner. There was a V-shaped tear in the liner on one of the upright "walls" of the multi-tiered pond, -and- the wall was wrinkled there - tricky. (Had to first use vinegar to get rid of white lime crusted onto the rubber from our hard water.) I had no rubber to use as a patch, so I cut a piece of fiberglass window screen mesh that was a little bigger than the torn area... First I daubed some of the adhesive onto the tear lines, enough to let it skush underneath a bit too; then pressed the screen patch onto this - and it held there nicely; then smeared a bit more over the rest of the patch to get it to stick to the full surface of the patch area, and let this dry overnight. (The window screen mesh was perfect to use, since it conformed to the waviness of the wrinkly rubber.) Next day I used a stiff piece of plastic (cut from a square plant pot) to -completely- cover the patch and its edges; waited another day (warm) before filling the pond... Success!

After using a variety of different products trying to patch a hole in our outdoor pond this was the winner! It was easy to use, dried and cured quickly, and the only thing that has worked to keep our pond liner from leaking. I put a 3 inch screw in the tip to cap the remaining product from drying out. We’re very happy with this product

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

Bonne qualité pour coller les joint des vitres pour aquarium

I had to reseal the inside of my 75gallon tank, this stuff worked great! used a little under half the bottle for all the seams! sealed another 10gallon tank a few weeks later with the leftovers, it worked fine too! I let my lager tank cure for a week, and my 10gal i left dry for a few days. vinegar smell is STRONG

Seams to be doing the job. I resealed a 75gal tank and it’s been holding for 2 months now.

This stuff allowed me to craft my own slate reef for a freshwater aquarium with like 200+ pieces. It is flexible which is good but also bonds very well, if placed properly it will hold some ridiculous stuff together. Since this is not fast drying, you can always use some support to hold a piece while it's drying if you are going for something crazy. I made a shrimp habitat that would put shrimp tank owners to shame from just buying easy stuff instead of crafting. Oh and I barely used like 1/3 of the entire tube for a project like that. Have fun?
