Customers say
Customers find the mineral cartridge works well, with one noting it performs better than bromine alone, and they appreciate its ease of use for spa maintenance. The product effectively maintains water quality, keeping it crystal clear, and is particularly suitable for hot tubs. While some customers find it great value for money and dependable, others consider it overpriced and too strong. The bromine content receives mixed feedback, with several customers noting high levels are unavoidable.
