Hello guys I have the jbj 65 aio tank....I have question about the aqua ultraviolet 2000+ 15 barb....I installed the intake pump for uv sterilizer where my pumps are for the tank in the middle chamber.....installed the return from the uv in chamber 3... is this the best configuration for this work? Is there a chance I am sterilizing water already sterilized? Thank for any help really appreciate it
