Hey guys...Been working in a hardware store for a few months now and my department includes the silicon stuff so I checked out the GE silicon I and II and both seem to have the meldewicide in them. Just noting this cuz i think i remember someone saying the sil I didnt...so maybe it didnt before but it does now. Aaaanyway im sure everyone is careful enough to read lables. Thanks for the time and keeeeep reading closely.

silicone I shouldn't... it's 100% pure silicone... did you check to see if it was the clear color... i know that the ones with colors on it aren't recomended for aquarium use...
