Silicone

[Charney]

I need to reseal a large tank and it has been a while since i have had to buy silicone. What are the recommended silicones to use now? Thank you

Two that I like are:

--GE SCS-1200 Construction Grade for large tank construction or resealing
--ASI Aquarium Sealant for tank construction or resealing under 24" tall
