Everything NEW April 2018. Selling due to relocation & lack of space. I was skeptical of how this type of pool would work...great. Uses resistance bands to swim against instead of a current. Includes complete pool, pump, saltwater system, 220v heater, & a year supply of filters for the pump. Saltwater system means no harsh chorine & tells you when you need to add salt, or if the water is too salty. Pool size is 7'x10'x4' deep. Have $2,000 invested in everything. NT for some reason won't let me put a link to the Fitmax site in this add. Rather than list all the specs here search: FitMax iPool3. If you don't find it msg me & I'll send a link directly to you.
