FreshWater Salt System Cartridge

Legit product

Actual name brand product, instead of the counterfeit versions on Amazon. Were even less expensive than others selling same legitimate product. Only disappointment is that manufacturer charge so much for such a simple product that fake ones are everywhere.

Not sure how to rate this, hot tub says change cartridge after owning hot tub for 1 1/2 months so I did, still says to change the cartridge after replacing with a new one. Neither cartridge has any evidence of limescale or anything else.

Regret

Way too expensive!
