GE Silicone 1 Black

[Cujo#31]

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.

Thank you.
