the current check valve works perfect. its a ugly noise as it kicks in but its doing good i guess. my checkvalve is clear would wrapping something around stopping the light from entering it help keep crap from growing in there and fouling it up? If your thinking of doing a divider tank on thing in my dreams i should have done if i had limitless cash is gone double width to 36". A 60"x36"x27" would be ideal in my mind so much more room.
