We converted our spa to saline last summer in the middle of the Arizona heatwave. We started with this product with great results. Unfortunately we made the decision to buy local and used a different product with rather poor results, continually needed adjustments made with chemicals, clogged filters, etc. Drained and cleaned the spa, started again with Bokek sea salts and the water is once again perfect going on 9 weeks now.
The Dead Sea salts raised my Hardness levels beyond 1000. I read they also have potassium and other minerals which might be therapeutic, but don't help your salt system create chlorine. Used pure NaCl instead.
Great product. Water feels great and stays very clear.
Put salts in my hot tub. Does help my chronic back pain and arthritic joints.
Love it!
