    Extreme CYA Flood Loss>>Don't let this happen to you

    Greetings. Just in case this happens to someone else-- Post-Harvey biblical rains I began a preemptive SLAM. My CYA had dropped to 30 from 40 pre-storm. From that point I kept noting extreme daily loss of FC and figured I had occult algae growth. CC averaged 1.0 - 1.5. Water became crystalline fairly quickly. Continued SLAM. One week into SLAM I ran another CYA: below 20, probably way below! Once I restored CYA, daily FC loss stopped. Lesson: keep checking that CYA . Best of luck to all Harvey and Irma members.

    We always recommend to check CYA after any large scale water exchange.

    Glad to hear Harvey was kind to you and your family.
