Return of the algae

In that case you'll want to take your FC to 20 or higher and do your best to keep it above 20 until you can go from sundown until sunup without losing more than .5ppm FC. Here's the chart and page that explains the calculation: http://poolsolutions.com/gd/best-gue...e-chart.html#a

Also, run your pump/filter 24x7 until you're finished.

Thanks for your help,algae gone ,water clear and bright. To bad the season is bout over here.I can see where I need to keep the chlorine level higher during the season. Most likely would not have had the algae problem with the higher level. I will use the suggested chart a reference.I'm also going to split the pump cycle to run twice a day. To all those with algae problems ,don't let the chlorine level drop to low! Thanks again.
