Hope this helps someone with the Polaris tying itself in knots. Here is my setup for a 15 x 30 ft pool with a 7 ft deep end. I have 4 swivels on my Polaris. When adding swivels, make sure the arrows on the swivels line up with the direction of the water flow (mine were wrong probably causing most if my problems).
Starting at the connection on the wall, I have a 2" hose connecting to the first swivel. Next I have a 5 ' hose to the next swivel with a float in the middle of the hose. I then have another 5' hose to the next swivel with a float in the middle of the hose. I then have an 8' hose to the next swivel with a float 2/3's of the way to the swivel. I then have a 1' hose to the backup valve followed by a 16" hose to the Polaris. It has been a week and no tangles.
Wall Connection -> 2" hose -> swivel -> 5' hose, float in middle, swivel -> 5' hose, float in middle, swivel -> 8' hose, float 2/3 down hose, swivel -> 1' hose -> backup valve -> 16" hose -> Polaris.
