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

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...

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...

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

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

Getting my pool in shape for summer, the pool chemistry looks good but I get algae dusting the side and on my vacuum 27k gal salt pool FC=3.5 CC=trace (barely pink) TC=4 pH=7.5 CH=276 (low end of normal) TA=70 CA=40 I recently serviced the DE filter. The salt generator (CircuPool RJ+60)...

Hi Marty, Quick follow-up. The DE filter crushed the iron precipitate and cleared it right up. I had to backwash it a couple times. I drained the pool about halfway and had city water trucked in then initiated the SLAM. The SLAM process went very quickly and I am now burning off the excess...

Do I start new water with SLAM, driving FC up? Or seek normal balance?

ok. Sounds like a water swap is still in the cards. It often dilutes down during wet winters, but we can't count on getting a wet winter and it could take years

What makes the iron appear as rust in the presence of chlorine? The pool water was clear until I elevated the chlorine level during shock then added new water. The new water in the 5-gal bucket was clear. As I added water, the pool turned green then nearly opaque rust brown

I neglected to include CYA. I assume I pulled about 4000 gallons from the pool. I got 110 CYA today. Tested it twice using the 2x method

OK, things are looking better. I still have a water truck scheduled for Friday, but a lot of the iron came out in the filter. If the iron is in solution and requires a water-change to get it out, why is it coming out of solution and filtering out like this? Yesterday afternoon I could...

i tried spot cleaning with acid in the past with little success From my research I would really like to get it kieresite blasted but I cannot find somebody to do it

As I get ready to pump and re-fill, my attention turns to the calcium ring around the pool. My wife called somebody a couple years ago who said he couldn't blast it without damaging the tiles. You mentioned the keiserite blasting but I can't find anybody within 2 hrs to do it...and they charge...

Ok, water truck can come Friday. Local HD pump pulls 3600gal/hr at 5 ft head...a bit less as the water goes down. I can't find anybody local that does kieserite blasting. I was hoping to get it all out of the way at once. I may have to figure out a DIY solution. Once the new water is in...

Hi NorcalX, it will cost me about $1500 to fill with city water from the hydrant. Marty, I have my DE filter on. I will pump out and the water truck is not available until Friday morning. Should I power wash teh pebble-tec prior to refilling? thanks Bob

Should I put polyfill in the skimmer? Get Ascorbic acid to dump in it? The weekend is over and I am back at work so I need to be efficient with my time here thanks
