    Dirty filter chlorine demand?

    Quick and maybe a paranoid question... Can a dirty sand filter cause a chlorine demand?
    I'm (hopefully) almost done SLAMming and I've been running my filter on recirculate just in case. Now I'm scared to turn the valve to filter, since I had clear water and high demand before - can the problem hide in the filter?

    Algae cannot grow inside a dark filter-----no light. Backwash it and filter.
