Use of algaecide

[waterbear]

be very wary of '3 month' algaecides...most of them are chelated copper sulfate. Copper is what turns hair green and it stains pool surfaces! As far as the CYA, I would recommend running ti around 60-80 ppm for Florida (I currently live in N. Fl but used to live in the Miami area so I know how the climate here affects pools!) The advantage of running a higher CYA and following the best guess chart is that you will not have to dose every day. You also might want to consider adding 50 ppm borate for it's algaestatic properties. If you want to but it from the pool store and pay a lot of money you can get Proteam Supreme or Bioguard Optimizer (both just very expensive borax or borax/boric acid mix for the pH neutral versions) or you could just get some borax at Walmart and some acid and do it for a lot less money!

As far as giving you amounts to use, you can use the bleach calculator which is in the Forum Q & A section. You put in your pool's volume, the percentage of sodium hypochlorite that the pool store chlorine has and it will tell you how much you need to add to raise your chlorine by XX ppm.
