    Frustrated while SLAMing

    Update-tested pool at night was 5.5 tonight with 0 CC. So it only lost 2 FC is 24 hours. Having trouble believing this is organic with that result. But i dont know why this is in the pool then

    Frustrated while SLAMing

    How would i even clean that? I took it off of the pool on purpose while SLAMing as I thought that the high FC levels could make it fall apart. If I did this whole process for nothing-ugh. It has a rip in it anyway so we are throwing it out when we close the pool.

    Frustrated while SLAMing

    So, the stuff is back. I haven't brushed the pool in a few days (but assume you aren't supposed to have to brush every day when not SLAMing) and the solar cover was on. I just took a peak underneath and see plenty of it again. Last night, I checked the FC and it was 7.5. The last time I added...

    Frustrated while SLAMing

    A little update-the last time I added any liquid chlorine was monday night. Yesterday I didn;t even test it because I knew I wasn't going to drop from 20 down under 6 in one day. So I tested tonight 48 hours later and am still getting a reading of 14 (it was cloudy/rainy all day today). Sure I...

    Frustrated while SLAMing

    Vacuumed and brushed about an hour ago. Backwashed also even though i backwashed after vacuuming yesterday (i normally dont like to backwash that often but in case any of the dead stuff was going to recirculate i wanted to blow it out) So i will check in a couple hours and see-thats plenty of...

    Frustrated while SLAMing

    Going outside to vacuum now. If that stuff comes back, i'll report that-dont know what the next step would be if it does is it normal to have to SLAM every year? I know pool school recommends SLAMing for opening and closing, but can i expect most (or every) year, this process will be necessary...

    Frustrated while SLAMing

    I was just following the extended test directions. It says to use 2 level dippers, but then later says "At very high FC levels it is likely that you will need to use more than the normal amount. " So if the normal amount is 2, then more than that is at least 3, right? Does the size of the drops...

    Frustrated while SLAMing

    Wow never heard anyone else say they had this also Just curious-you say that the SLAM worked for you, but you still have the dust/particle stuff? Was the SLAM for something else or for that and you just gave up after that long? (I cannot imagine doing this for a month-the $ on LC and running...

    Frustrated while SLAMing

    Ok so maybe I am done? I was afraid of landing in "maybe" land. I woke up super early to beat the sun and check-i SLAMed to 20 last night i tested and got 18.5-wow what a punch in the grapes, 37 drops was the worst possible number, but i do it again to confirm and keep getting different numbers...

    Frustrated while SLAMing

    It is above ground. No lights and the ladder is brand new this year (I needed a new ladder anyway, but was hoping that when I threw the old one our, the problem would go away). I actually did just soak a scour pad in bleach and clean the skimmer mouth as well as brush the walls

    Frustrated while SLAMing

    Ok so today lost 2 when i woke up-added it vacuum/backwash/brush at 2:30 test again at 4:30-down 7 fc from 20 to 13-added 7 This is crazy-i keep wondering if what i am seeing is dead algae, where is the live algae that is dying and apparently has been for 2+ years? Ladder is new this year so it...

    Frustrated while SLAMing

    Side note, in the beginning of the season, i used a bunch of MPS (non chlorine oxidizer) at the advice of the store (before i got my TF100 and advice here). Article says that MPS can show up as CC. But that was 8 weeks ago is there any chance that is still in the pool and skewing my results or...

    Frustrated while SLAMing

    Yes, so i woke up today and lost 2 FC again. Problem is, the light was on the pool for 3 hours-so again there is a confounding variable. I'm still at it, but it is just frustrating because the pool water is so clear it is almost invisible at this point, so i cant believe there is a problem, but...

    Combined Chlorine Problem-help!

    @jblizzle I am presently doing a SLAM again-i see in pool school that MPS will throw off/count as either FC or CC (there must be a typo because pool school says both). It has been like 7 weeks since i added all of that MPS-is there any chance that is still in the pool and skewing my results or...

    Frustrated while SLAMing

    @setsailsoon Yes I am filtering 24/7. Pressure seems fine. I have maybe a touch more than 40 CYA so I am SLAMing for 50-there is a chance my CYA is 40 or less as I mentioned i hate that test. but even if my CYA was really low, i shouldnt lose FC in the dark (I'll test around 11pm before bed so...

    Frustrated while SLAMing

    Several points, but all related: So, I am a bit frustrated with the SLAM process. Let me clarify I am grateful that I was taught this, but anytime I am doing it (like right now), I end up with a million questions, most stemming from when I am done. Now I understand and have read the 3 criteria...

    FC loss scenarios

    Hello All, Had a couple questions regarding FC loss 1)Got (over) thinking about something I have been wondering for a while: On a normal day, I would dose the pool to get it to 6ppm FC and 24 hours later it was usually around 3FC, which I believe to be in a normal/accepted loss. (lost 3ppm or...

    Pool Math Glitch?

    What do you mean-could you explain this more? It looks like you mean if you dont have to change the CYA value on the FC page it is correct, but isnt that the same as me changing FC last?

    Pool Math Glitch?

    And also keep your FC numbers the same and keep increasing what your CYA is-the amount it tells you to add will keep going up which mknauss just told us is wrong and CYA should not change the amount of bleach you need to add to get to a certain FC amount

    Pool Math Glitch?

    This is my first year using liquid chlorine so I have no idea if 3 or 4 cups is too much for a 10,000 gallon pool to add 3ppm. I have just been adding 3 or 4 cups per day as it has told me. But I would assume it is not giving me the upper limit of the FC recommendation based on the CYA because...
