I just used TSP on my Nordic hot tub filter and it is GREATTTTT!!!!! Used two gallons of water to one cup TSP and soaked for 24 hours. Then sprayed off with hose on jet and soaked again in fresh water for two hours. Repeat the soaking again for two hours and sprayed with hose each time. The filter input area is drawing water like I turned on the disposal in the kitchen. Thanks for the great money saving tip.
