Happy new year fish keepers, one wee question does anyone on here have a Fluval Shaker aquarium I'm might have one, regarding the inlet and outlet tubes they have two rubber rings on each tube, does on remain on top and do you take the other off, and put it underneath then screw on the ring nut, or do you leave the two rubber rings where they are insert the pipes and screw on the ring nut, hope this make sense, I've downloaded the instructions, but the section on the pipes is a bit vague.
