    To SLAM or not to SLAM....

    Pool was finished 9-1-15 and we have been trouble-free until the past couple days. Might still be ok, but I'm wondering...

    Most important - here are my numbers - just tested about 10 minutes ago: (I do have the proper test kit - I know sig says 2005 kit but I ordered the extra that I needed from TFT)

    FC 6
    CC 0
    pH 7.6
    TA 70
    CH 160
    CYA 60 (maybe 70 - I hate this test.
    Salt 2800
    Borate 30
    Temps have been running 86 - 90 - closer to 90 consistently.

    I also did a OCLT last night and the pool lost exactly 1ppm.

    Water is clear but the past couple days I've brushed off some green spots that have me nervous. And like a dummy I didn't take a picture. Also - we have these lights in the pool:

    Product Detail Overview PAL

    And when I'm checking them out underwater I see green film in the little circular spaces. I don't currently have a brush that will fit those tiny little spaces - on the hunt and welcome suggestions. Toothbrush is too large...

    So I'm nervous and wondering if I should perform a SLAM just in case.

    Thank you for listening! And please forgive me if I posted this in the wrong place...

    Sara, if you saw green that quickly clouds or "poofs-up" when you move it, it's probably algae. If you saw the same material around the pool as if it was pollen, then you could consider that as an option. Otherwise ....SLAM. Don't wait. It won't hurt anything. You can still use the pool. With a CYA of 60, your SLAM FC level is 24. If you determine CYA to be 70, increase FC to 28. Don't forget to lower pH FIRST to 7.2 before increasing the FC though.

    As for the lights, I have about the same type. Not much you can do other than remove the protective lens and wipe it off. You can't really do much with the fixture protruding from within the FB wall. The bleach will take care of anything in the water. Make sure to hold the FC until you pass the 3 SLAM criteria.

    Thank you so much for your reply Pat!

    The algae vs pollen has me wondering too. Would pollen "poof"? This material - whatever it was - definitely "poofs" when I mess with it - whether it's my foot "stomping" near it or the brush. I haven't seen the offending green since Thursday.

    SLAM it is! I don't want to take any chances!!

    One thing you could do is the OCLT test, but if I see anything green in my pool I too will slam right away...

    Re: To SLAM or not to SLAM....

    Ok, so for my sanity and to make sure I don't mess this up - here's my "SLAM diary":

    Knew I wouldn't have the time to properly tend to this the past couple days so just started my SLAM today.

    Tested this am and added bleach to bring levels to:

    9AM:
    FC 26.5 (was shooting for 24)
    CC 0
    Brushed and brushed and brushed! Pump is on high and I also turned on the deck jets for about an hour to let all that good FC circulate thru them. I have turned my SWG off.

    10:45AM tested:
    FC 22.5
    CC 0
    Added 43oz bleach to bring back to 24ppm

    3:30PM
    FC 18.5
    CC 0
    water temp 94
    Added 156 oz bleach to bring back to 24ppm. Brushed again.

    Note: today has been a FULL SUN day and our pool gets hit with it all day.

    My thoughts: last night while swimming I brushed around all the little light places as well as all around our steps. No ladder in the pool - just the built in steps. Saw little "poofy" areas as I was scrubbing those couple places - no other visible green yucks as far as I could tell. Ran the Dolphin overnight as well.

    Will check the levels again after the hubby gets home (5-7pm-ish) as we always jump in as a family to cool off - want to be sure its not above SLAM level so that it's safe for swimming. Water looks great.

    Plan:
    I *hope* this is a SLAM out of an abundance of caution. I plan to keep checking the FC level and adding bleach to keep it at 24ppm. As long as I don't see any more signs of algae and my CC stays at 0.5 or below and I pass the OCLT tonight - is it possible this will have been a 1-day SLAM?

    I am so thankful for this forum. Off to donate in a bit!

    Update:

    7-27-16
    6:30AM tested:
    FC 21.5 = loss of 2.5 overnight
    CC 0
    Added 185 oz bleach to bring FC to 28ppm. Thinking my CYA really is 70, not 60, so using 28 as my new target.

    7:50AM tested:
    FC 28
    CC 0
    brushed again, extra attention to skimmers. Water definitely looks more "sparkly" today. It's funny how you get accustomed to looking at the water every day and "forget" how it's "supposed" to look. My water hasn't been looking bad, but compared to now it was definitely a little dull.
