Turns out my water is a bit on the hard side as my calcium levels are high upon each drain and refill. I'm running a 2020 Envoy with salt system. The Vanishing Act pillows cost about $77 per 1 time use. I drain and refill about 3 times/year so it adds up.
I've been researching the On the Go softerners. Prices and options vary so curious as to which On the Go product works best for a 390 gallon tub?
I don't have the need or want to buy an entire house softener, the water quality from my tap has won awards for excellence in the nation. But I guess its a bit hard for a salt tub according to my research. For $300ish the unit would pay for itself in about 1 year, so leaning toward the On the Go method.
Thanks!
