I used this for about 4 years. Worked flawlessly.
Connect 6 x 50 foot black rubber garden hoses (not included),
and lay them out in the sun near the pool.
Can be coiled into a large circle for a smaller footprint.
All of these parts were over $100 alone apart from the labor.
One of the female/female connectors is missing. (around $4 at home depot

Will need appropriate connectors to your pump/filter
