All Necessary Chemicals & 14 filters to maintain your HOT TUB, WHICH I no longer need because my hot tub is gone. These chemicals were purchased at the pool & spa depot on South Willow and the filters were bought at Amazon; all within last 3 months, costing over $136 including tax. I weighed each item with results marked on each (SEE PHOTO), so you have a comparative of amount remaining; which is well over the average of plus/minus 85%..
