    Algae back. SLAMed mid April, chemistry looks great. Why is it back?

    How long should I maintain SLAM FC levels before letting it drift down?

    Algae back. SLAMed mid April, chemistry looks great. Why is it back?

    I set up the controller program 20 years ago for my my old Hayward SWG, so my memory is a little foggy. Also, the Circupool generator operates a little differently with the controller, with more local control on the Circupool unit. At the time I set up the program, it had multiple loops at...

    Algae back. SLAMed mid April, chemistry looks great. Why is it back?

    As I noted above, my pump runs most of the day at slow speed and at high speed for several hours each night. My old Hayward SWG was programmed into the controller to run at night and some during the day, and I don't remember the program loops because it has been a long time since I went into the...

    Algae back. SLAMed mid April, chemistry looks great. Why is it back?

    Good advice. I'll SLAM again and run the SWG a little hotter, plus check throughout the day a few times to better understand how the FC ebbs/flows through the day thanks

    Algae back. SLAMed mid April, chemistry looks great. Why is it back?

    Thanks. FC is my first reaction too. I test Cl every few days and it is stable, in the 5-7% range (a little higher than target for salt pool). I shouldn't have to maintain it higher than that...and I target the 4-5% range. I have the Circupool SG set around 30% duty cycle. I run the VS pump on...

    Algae back. SLAMed mid April, chemistry looks great. Why is it back?

    I SLAMed my pool in mid April after re-balancing pool chemistry after winter rains. Turned salt generator off, OCLT quickly stabilized, I let CL drift back to normal, and thought I was good. It's now mid-June and algae is back. Why is that? Not bad, but I see algae when I sweep the walls and...

    SLAM duration

    I get lazy during the winter, when the pool is not used and the water is very cold. The rain dilutes the pool and I don't like adding chemicals that will dilute out and go into the ditch out back (I am on a rural property) after every big storm. The pool water is cold enough I don't get algae...

    SLAM duration

    I apologize for not being more clear in my initial post. To answer TX Splash's question, I went into SLAM as part of my spring opening process. With 40 inches of rain over the winter, I let my water get out of balance (water temp around 50) and I use the SLAM to get me started with a fresh...

    SLAM duration

    Duraleigh, can you be more specific? I am confused by your reply I read the SLAM article - I have a TFT pool DPD test - I did forget and raised CYA from very low to to 60. That was my only deviation from recommendation - For that CYA, PoolSchool recommends FC 24 (Free Chlorine and Cyanuric...

    SLAM duration

    Getting my pool ready for summer after 40 inches of winter rain. TA, pH, and CH dialed back in very quickly using PoolMath. I took the CYA to around 60 before re-reading in the SLAM instructions to keep it low. I will raise it a bit more when done with SLAM. How long should I expect to...

    spring start-up

    Re-balancing after winter rains (N Cal). I have a little algae on my vacuum, but pool walls look good and water is clear. My latest test results... - pH 7.5 - FC 5.5 - CC 0 - CYA 60 - TA 50 - Calcium 300 Salt pool I was expecting to SLAM it to get a good baseline, but given the readings I...

    Looking for thoughts on water balance

    Fill water from my well, cleaned through water softener, calcite filter, and CL injector. I measured pH 7.5 from the hose bibb early this morning. The auto-fill pulls conditioned water from the same bibb. For TA, measured 110-120 (barely red at 110, red at 120) for TA. This may explain why...

    Looking for thoughts on water balance

    Hi Marty, Quick follow-up. I pushed pool CL up to 9ppm with 1/2 gal of liquid chlorine (left over from my well) and increasing my SWG duty cycle. Acid brought pH down to 7.5. Last night turned SWG off and tested...it took 19 drops 871 to clear. This morning used 18-19 drops of 871 to clear...

    Looking for thoughts on water balance

    Thanks, Marty. I'll bump the SWG up to increase FC. If I have a recipe for algae brewing, should I SLAM it again or watch it for time being? Also, how would I have known I have recipe for algae brewing? I aim for the bounds listed in TFP and by the Circupool manual (slightly different...

    Looking for thoughts on water balance

    SLAM'd my pool in late May because of some algae; took FC up to recommended 24, stable overnight, then let it drift back down. Pool looks great. Pool still looks clear. Kids are gone so not much use this summer. My wife brushed pool today after about three weeks. She said there was a...
