Why can't I use regular 100% silicone in my sump? I have used perfecto aquarium sealant which on the container states that it is 100% clear silicone rubber. Sooo what is the big differance between aquarium silicone
and standard silicone? Both are 100% pure silicone. Is this like when the southdown bag says not for aquarium use?
