Thread: Dirt or something else?

    Dirt or something else?

    Hey guys, pools sat with the filter going 24/7 with the solar cover on for the past couple weeks and I came out to this mess. Waters still crystal clear, FC was at 4.8, CC was at 0. CYA is around 40.

    Is this just dirt? I've been fighting this on a small scale all year. Never looked this bad though. Anything else I should be doing?

    Thanks!

    That looks a lot like algae. How often have you been brushing? Has your FC fallen below target recently? Best bet is to bump FC to 10 and do an OCLT. What are you using to test?

    Dirt or something else?



    FC is good and there's no CC though, thought I'd be in the clear. TBH since starting TFP (since day one) I've never brushed it, never had to (or so I thought). This is the end of the third season. Or I should say I don't scrub the walls anyway. I've suck up the visible dirt on a regular basis. I have the cleaner tool running now and the slime bag connected. Added one gallon of bleach.

    I would brush it, then run your OCLT.
    L brushing is part of the recommended weekly care, in Pool School. It helps break the biofilm so the chlorine can attack it better. I find I need to brush more often when the pool isn't being used. (Guessing the feet allow over tend to have the same effect as brushing, lol.)

    if that is tree debris, the brushing will help get it up into circulation and lets the filter trap it. If it is algae it lets chlorine get to it and the brushing disrupts any biofilm algae makes to protect itself.

    Either way you really ought to brush now and then, 'k?

    Will do.

    Tree debris, never heard of that. Are you talking about normal leaves etc or do they produce a dust like that? We have a large oak tree right next to the pool.

    We get pollen from our pine trees in June. It will cloud the tree line with yellowish powder when the wind blows. It then covers everything. The porch, the car, the pool cover, etc.

    That is algae in your pool. Mostly dead but it looks green enough for some to be living.

    You need to SLAM the pool (which includes brushing) and then you need to manage your pool water by doing all the right stuff (filtration, brushing vacuuming keeping FC in the pool)

    Once you finish the SLAM, your pool will sparkle and your continued good maintenance will keep it that way.
