We got a 718 gallon stock tank from UW Surplus for less than half of retail. We bought a cheap chlorine floater at Walmart and a solar cover from Amazon for $20. I plan to spray paint the outside oil rubbed bronze so it’s darker, attracts more heat and just looks nicer.
The big kids (plus a neighbor kid) have played in it off and all day. Maybe one day we will add the redneck hot tub heater too it.
