Ah, okay thanks. Shortly after i asked you my question i actually realized just about every silicone sealant says "do not use below waterline". An associate in Home Depot actually told me "all silicone shouldnt be used below the water line". I then asked him, then how come every fish tank that has ever been made has silicone that goes below the waterline and stays below the waterline for an extended period of time. His response was "you got me there"
My best friend was actually flirting with him earlier and i told her hes not worth her time. ;)
