Tonights project will be resealing my tank. I understand that I have to use 100% silicon but is there a specific brand that people are having the best luck with? So far the only brand I've read about using for this project is "GE Silicone I". Anybody else try this? Whats the difference in using either the "GE Silicon 1 "kitchen/bath" or the "Door/Window"? Also, my tank is 72x18x18. How many tubes should I be looking to bring home to do this? Thanks
