    SLAM Question

    When I opened my pool, the water was clear. During the 5 days that the cover was off, I threw some bags of shock in there (leftover from last year) and added some bleach as instructed on here daily until the pool company came to show me how to start everything up. That being said, do I still SLAM if the water is somewhat clear? I tested tonight just the FC (4) and CYA (30) but am curious if I need to bring the FC up to shock level at 12.

    The best way to tell if there's something growing in your pool is with an Overnight Chlorine Loss Test. Unless you can see algae or feel the sliminess on the walls, then you know you have algae. If you fail the OCLT, you need to SLAM. 30 CYA is perfect for that.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    The FC went down to 3. Do not SLAM?

    Have you measured the CC as well? As long as your water is clear, your FC loss was 1 or less and your CC is 0.5 or less, then no need to SLAM.

    No CC's so I guess I'm good. No SLAM.
