GE Silicone 1 Black

[kookie_guy]

One very important thing nobody has mentioned yet, is that there is a big difference between the GE I silicone and the SCS1200 silicone. The GE stuff is a silicone SEALANT. The SCS1200 is a silicone ADHESIVE. 2 very different products. If you are just sealing an already built aquarium, then yes, you can use the GE I stuff if you find it in the colour you want. BUT, the sealant has very poor strength properties. The SCS1200 adhesive is what's used for building and sealing aquariums because it has excellent strength properties. The guys that are experiencing failures are the ones using a sealant to build an aquarium. Put the high water pressure on the glass and it will come apart.

Go to auto parts store. They sell pure silicon in black. 6 bux a tube verses 11-13 a tube for "aquarium silicon" which is.......pure silicone sealant. Off the shelf stuff at hardware stores 99% of the time only carries silicon with algicides.....bad for coral.

Btw, I have 3 tanks, 90 gal plus, all either built or re sealed with pure silicon form auto parts store........no failures. Just make sure u remove ALL old silicon u can get to, clean VERY WELL with pure alcohol, and dont allow silicon beads to from "skin" or ur screwed and will not get good bond bead to bead, and "tool" bead to make sure good contact with glass. (I use my finger).Mask area ur sealing to minimize mess but dont worry too much. Once silicon cures messes are easily cut and cleaned off wiith razor scraper.

I bought newflex 333 aquarium silicone $5. They do have black color though.

Thank you.
