Why You Need It

Saves Money


Chemical Costs Per Month!

An average 20,000 gallon pool requires $40 of chlorine per month. If the weather is hot and sunny your chlorine cost can triple and exceed $120 per month! Our photolytic process also helps maintain balanced pH levels, so you save money on pH UP and DOWN chemicals also. Less chemicals also mean less corrosion on pool parts. In the end, Card On Guard can pay for itself in a matter of weeks.

Less Maintenance

All you have to do is place Card On Guard in your pool or hot tub and let it go to work. Simply check your free chlorine levels regularly as you normally would. Because Card On Guard is doing minimum 50% of the work fighting bacteria, you have less of a fight controlling bacteria in your pool or hot tub. Card On Guard also helps maintain stable pH levels reducing the work even further.

Healthier Bathing

Card On Guard reduces the need for harsh chemicals like chlorine which create chloramines, a byproduct of Chlorine combining with ammonia and nitrogen in the water, that are released into the air and are strong respiratory irritants. Chlorine is also drying to the skin and can irritate existing dermatitis.

More Natural and Enjoyable Water

Less chlorine means less chance of that “chlorine smell” caused by chloramines. Water that contains less chlorine is also often described as less drying and less irritating to the skin… so less chlorine, more natural and enjoyable bathing experience.
