kudos! this is the method I like. never need to shock or use an algaecide.
however someone told me that I should be keeping my chlorine below a certain amount as this is law. Is there a law that prohibits maintaining a pools chlorine level above a certain amount?
Thanks.
As far as I know of, there is no "law" governing the use of chlorine levels in a pool. This is something you would have to check in your particular area, however, I also don't know why anyone would want an abnormally high concentration of chlorine as this does just as much damage to your pool surface as having too little sanitizer with an algae infestation.

amount of FC needed to sanitize and keep algae away is calculated from a % of the CYA. If CYA is high then more FC is required. However from what I've gathered if an algaecide is used less FC is needed. Only problem with that is copper build up and possible staining. Might as well go with an mineral ion solution one time (chlorine free). Just best make sure you have a really accurate copper test kit and keep pH on the lower side.
Thats only if you used a copper based algecide. Copper sulfate is used as an algaecide in the treatment of surface waters such as reservoirs, lakes and ponds. It should not be used in swimming pools At the pH of a typical swimming pool and in the presence of chlorine or other oxidizing agents, copper (from copper sulfate, natural sources or corrosion of heaters) can and will cause staining and discoloration of pool surfaces and hair. Of course there are people that use it in pools and have no problems. But why risk when there are other better products.
