    Do I need to SLAM?

    Hi there!

    I've recently noticed a small amount of greenish algae (or what I assume to be some type of biological material) at the bottom of my pool, hovering around the center drain. The rest of the water is clear and sparkly, and this morning's levels are as follows:

    FC 3.2
    CC 0
    pH 8
    TA 100
    CH 360
    CYA 30ish
    Salt 3300
    Temp 76

    I have persistently high TA, which is why my pH drifts up so much, and I add acid about every other day. These results are from before I added acid this morning. Also, I'm aware that I need to add some stabilizer to get that CYA up, I just haven't made it to get some yet this season.

    If I can remember how to add some pictures I will, but since my water is clear and my CC is zero, do I really need to go through the SLAM process? Would I need to do an OCLT to be sure?

    Thanks,
    Chelsea

    I'd go ahead and SLAM. Check FC & CC tonight after the sun stops hitting the water and check it again in the morning before the sun hits it again (pump on all night) and if it passes the OCLT then you've just had the shortest SLAM in memory.

    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!

    Can't tell if for sure, what's on that net, but did you have a baby in the pool wearing a regular diaper rather than the ones designed for swimming? That happened to us before and the stuff from the diaper looked just like that. I slammed it on principle. lol It was only a 1 day slam, but better safe than sorry.
    I'm slamming as we speak for a different reason, but like Richard320 says, "Nip It"

    No babies in the pool yet this season (water temp not quite warm enough here), but I can definitely see the resemblance to diaper fluff Last season around this time I slammed, just to find out that it was a green pool noodle that the dogs had shredded and the foam blew back into the pool and sank to the bottom - lol! THAT was the shortest slam in history.

    I'm just gonna go for it to be safe. Thanks for the advice. Oh, and I'll need to shut off the SWG overnight for the OCLT, right?

    Yes, turn SWG off, but leave pump on. You want it to hold on it's own overnight. LOL on the dogs and the noodle. I figure if have to ask, "should I slam?" I probably should.
