The GE silicone type II (i belive this is supreme) is ok to use. Many here including myself have used it for sumps. GE silicone type I should not be used
This is wrong. Type 1 is the correct one to use. Type 2 is the anti mold and mildew which is bad to use.
Some will get 100% aquarium safe silicone but i have always used
