Description
When used initially with new water in hot tubs, use 1/2 of the bottle, then clean your filters 2x in the next 24 hours - This product will take the liquid metals out of solution and bond them so the filter can trap them. Depending on your metal content in your source water, you may need to do this more than one or two days.
Also, used in swimming pools for the same purpose, add then clean / backwash your filters to remove the bonded particles of metals.
Remember, your sanitizer will react with metals in your source water and this will give your water often a "green" look, often mistaken for Algae.
