Hi,
A question...do you have any black particles in your pre-filter? The reason that I ask is that algae is usually only a problem in hot/humid areas. It was a common problem when I worked in Florida and Atlanta, but we just don't see it up here in Wisconsin, so nobody stocks alge treatments.

Regards,
Randy D.
