    Crystal clear pool, high cloromines?

    Hi everyone. I am helping my inlaws with their fiberglass pool. It was a swamp and we have been slamming for a few weeks. We finally have the pool crystal clear, it's gorgeous. Last night the chlorine was brought up to shock level at 8:30pm and at approximately 2am it had drifted down from 15 to 12. Everyday I check cloromines and still seem to stay between 1.5 and 2. I don't see any dust or cloudiness and no algae. Is this just tail end of slamming? Thanks for your help.

    Chasing the last bit of algae is maddening. Now is when you check inside and beneath ladders and steps and lights and scrub 'em out. Also worth considering: have you added any non-chlorine shock products? The MPS will interfere with the CC test.

    What is the CYA level? I know a couple years ago one guy had to finish his SLAM -- also lingering CC despite everything being spotless-- by taking it up to Mustard Algae level. He must have had some pretty hearty algae strain growing.

    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!
