    Hints of Algae...do I go to a full SLAM assault?

    Good morning forum,
    Checked on our IG SWG pool this morning and I saw just a touch of algae on the ladder. Chems have been consistent and I will post below. The CYA dropped to 55ppm with the recent rain but I have adjusted for that over the last few days and I am sure it will be climbing as it's digested. Water is still clear, not cloudy. So my question is, should I worry about a little algae on the ladder or should I launch a full SLAM assault or is the answer in between somewhere? Thank, you folks.

    Current chem levels are in my vinyl, SWG pool...

    FC 6.6
    CC - 0
    PH - 7.8
    TA - 90
    CYA - 55, just added recommended levels to get it somewhere around 70-75ppm but it takes a few days to show I think.
    CH - is low around 70 I think but I rarely check it because of the vinyl and I read it here it doesnt have much impact on vinyl liner pools.

    If you have visible algae you need to SLAM. You want to kill everything off so to do that you need to SLAM.
    It should go quickly. 😎

    Visible algae....SLAM. It's likely to be a short one for you if you follow the process to the letter. Better to catch it now than to take the chance of the whole pool being green, right?

    Thank you and I tend to agree but what if I'm already passing all the criteria in the OCLT?

    Doesn't matter. Visible algae equals a SLAM.
    Get it now before it gets out of hand. It should go quick.
    It's what I would do. 😎

    Just curious- how did you make out? I'm going to a pool party today at a friend's house who went through the same exact thing. Not sure if I should let my kids swim in the pool. Hopefully they won't be offended when I show up with my test kit.

    Also, if the algae is only a little bit and always in the same spots, then consider improving the circulation in the area.
