silicon

[JOEL]

I am going to reseal an aquarium what kind of silicon should I use?

Aquarium silcon anything else can leach back into your tank

As long as it's a non-toxic, 100% silicone sealant, it should be fine. Non?

GE 1200 construction silicone is what most tank builders use. You can also try some of the GE Silicone from the hardware store but you need to get the one that doesn't have any mold inhibitors. I don't remember if it is GE I or GE II, definitely not the kitchen and bathroom stuff. Most stores will carry smaller tubes of silicone from All Glass or somebody else, these are usually expensive but the easiest way to go ahead for sure.

GE1200 is nearly impossible for the average joe to find around town.
I've been using a mastercraft brand from Canadian Tire. It says right on the back that it is safe for aquarium use.

if i recall correctly from the last time i use any, GE Silicone 2 for windows and doors should be safe. can anyone else confirm?
