Works great A big help with spa maintenance.

Great pricing.

Bought this and after using it for a month, I have a blue waterline around my spa and both filter cartridges are stained blue. Tried soaking them, did nothing. Tried rubbing out the stain around my spas waterline, did nothing...not happy. Very disappointing because everything I use from spa depot is great, just not this.

I have been using this product for several years. I definitely recommend it for spa use.

Will call again!

Since using the Spa RX mineral system chlorine costs are half what they use to be I cant brag enough about this product. No longer have the chemical odor.The Spa is so much more enjoyable Recommend this product to all spa owners.
