    Stuff on the bottom of the pool

    Current test results
    Fc 4
    Ph 7.6
    Cc 0
    Ta 90
    Cya 50


    I've vacuumed this up. I even elevated the fc to 12. Naclo consumption seems normal. I initally thought this was sediment from pollen.. But I've no idea.

    Help because you guys rule and always solve all the problems.

    Well right off the bat your FC is too low for your CYA level. So certainly could be algae. And 12ppm is not high enough to reach shock level for your CYA level. So, I think you need to properly follow the SLAM process.

    Yep what Jason said. Your SLAM level is 20. You can take it a tick or two higher. You need to maintain that level until all three criteria are met.
    Water is crystal clear.
    CC's of 0.5 or less.
    You can pass the OCLT. 😎

    Re: Stuff on the bottom of the pool

    One last question. Why is my CC still zero.

    I use a 10ml sample and drop the the 5 drops to test for CC.

    0 is ideal. Why do you want it higher?

    Re: Stuff on the bottom of the pool

    I know it is ideal. But I was mistaken to think that if algae is present it would be higher than 0

    Algae does not always result in CC. There is a reason for 3 different criteria to stop the SLAM process.

    You don't have a swamp going on so this should go pretty quick. If this is algae just maintaing proper FC range won't get rid of it.
    If it's not algae all you lost was a couple jugs of bleach.
    SALM the pool and either way it's a win and peace of mind. 😎

    Re: Stuff on the bottom of the pool

    If you have enough bleach on hand now, you could do a OCLT Test to confirm if something is consuming chlorine or not.
    Just an idea. 😎

    Nice work!

    Now keep that FC high enough and you should not have further issues.
