Is the chemical that you use - safer? If so, what type of chemical are you using, I may give it a try. Also, how much does it cost per sqft compared to chlorine?
I've been searching for an alternative that compares in price and quality. The quality will be hard to beat, but maybe if the price is lower - it may be worth a try. Also, if it is safer, thats a big plus. Eyes and lungs are pretty important - although I havn't heard of a big epidemic in the pool industry, pressure washing industry, or people who maintain their own pools at home. When I go swimming and the pool has too much chlorine in it - it sure burns. So therefore, I were goggles and a face shield.
I too, say be careful with any chemical, especially chlorine.
