Ionization is an effective and inexpensive way to keep a pool sanitized. When combined with chlorine, it acts as an excellent deterrent to algae growth and kills all viruses and bacteria. It doesn't irritate eyes or skin and does not change the pH of the water, unlike salt chlorination, which constantly raises the pH and requires careful control to keep it at the optimal level. Keeping the pH neutral is also easier on your pool equipment.
To ionize your pool, simply drop one tablet of zinc chloride into the skimmer weekly or biweekly and you have a complete solution that is totally noncorrosive, unaffected by sunlight and lets you reduce the chlorine concentration by up to 40%.
The ionizer will build up copper, zinc and silver in the water. Whenever you add algaecide to the pool, it's mostly copper based - the copper kills algae, zinc prevents staining and silver kills bacteria. With the ionizer system you get all the benefits of traditional sanitation without any of the negatives... which is the reason ionization is considered to be the best solution for sanitizing your pool!
