algae problem for months

Maintaining adequate chlorine (> 2.0 ppm where CYA = 0) should prevent the algae from regrowing. You can do this with 6% plain household bleach. Note that chlorine levels will drop RAPIDLY, once post-storm clear skies arrive, so add daily bleach doses late in the evening to allow them to work all night before being destroyed by sunlight.
