Spa Marvel Cleanser is a fast-acting proprietary cleanser that penetrates deep inside of your spa’s plumbing and equipment, caustically removing biofilm, organic, mineral and chemical contaminants. In brand new spas, Spa Marvel Cleanser removes residues leftover from the manufacturing process including waxes, oils and resins.
Heat spa water to desired temperature. Add one full bottle of Spa Marvel Water Treatment to all tubs up to 500 gallons (2000 litres). Even in smaller tubs, use 1 full bottle as your bather-load per volume of water is usually equal to, if not greater than the larger tubs. (In a brand new spa, add one third of a bottle, the second third in 30 days, and the last third in another 30 days.) Occasionally when theSpa Marvel is added it can be seen as white strands suspended in the water. This is normal and the Spa Marvel will go into solution once it has had a chance to circulate.
Balance alkalinity (80-120) and then pH (7.2-8.2) if necessary using traditional spa-water balancing products available from your professional spa retailer. The acceptable range for pH when using Spa Marvel is much broader than when using traditional spa care products, so please take care to read your testing devices properly, keeping in mind that they are calibrated to show the “OK” range when using traditional chemicals, not Spa Marvel.
Traditional spa treatment products work best at specific water-hardness levels. Spa Marvel will work at any hardness level, and given the choice Spa Marvel prefers softer water over harder water, but it is not a requirement. If your source water is so soft that it is corrosive and damages your heater and seals, then please adjust the hardness using calcium hardness increaser as per your professional spa store’s guidelines.
