Spa Marvel hot tub water treatment is one of the easiest and safest water care systems on the market today. Your spa's water will be softer, clearer, without odors nor foam and won't irritate your eyes and skin. Users report that frequent Spa Marvel-treated spa and hot tub use leaves skin feeling soft and moisturized. Spa Marvel's unique blend of natural enzymes, minerals and plant extracts contains no harsh chemicals. It is made with natural compounds which condition your skin and is a completely natural and safe alternative to traditional spa and hot tub care by drastically reducing the amount of chemicals you use in your water.
One full bottle of Spa Marvel treats any tub up to 500 gallons, and lasts 3 months with regular use. Every 3 months simply add another bottle, and you can go up to a year without changing your water. You do not need to change it as often as you typically would, as you are not super-saturating the water with all kinds of chemicals on a routine basis and the TDS (total dissolved solids) of the water increases only marginally.
so easy to use. no smell, no smell, and no smell, did I add, no smell? very pleased with this, i have been using it for years
This product is awesome!! works exactly as advertised. no more checking water balance every few days. Just make sure the PH is right and add more three months later, it's literally that simple!!
