Installed new filter. Began Slam process with super shock 1lb. (7ppm per lb). And liquid chlorine up to 14ppm FC. (Cya 33). 1lb bag of Super Shock actually brought FC up to 12ppm. Tweaked with liquid chlorine to exactly 13.5ppm (27 on test) and will maintain this amount. I’m guessing my total gallons is slightly less than 10,000 in the pool.

1/2 drain and refill to lower CYA. Successful @ 60ppm down to 35ppm. Reduced PH from 7.7 to 7.2 prior to SLAM. All remaining parameters nominal with new water. Replacing the cartridge filter with a new one and turning off chlorinator during during process.
Cleaned out all filter baskets at skimmer and pump. Flushed pump filter basket housing. Will flush cartridge housing as well.
Will complete SLAM process based on cya levels. 16ppm is my fc slam level. Will add liquid chlorine twice daily or as needed to maintain until process is complete.
Brutal hot summer days with no rain = About 3-3.5ppm chlorine depletion per day using mix of tabs and liquid. So when shocking maintain at or better than shock call here until algae is gone. Example Yesterdays level was 19.5. Today @16.

First test since Hurricane Ian partial drain and half refill. Drained down to just above return jets then added back up to halfway on the skimmer with no rain in the forecast for awhile post storm. Ph levels look good and stable. Ch went up a little as did TA levels. 👍🏻

All still very stable after a month. Ch has decreased slightly and cya has failed to rise at all. Steady at 35. Need to add some stabilizer conditioner to raise cya slightly. Otherwise looking good. Scaling seems to have tapered off as well. 👍🏻

All still very stable. Ph and Ta maintaining stability at 7.5 and 60 with no chemical additions used in a few weeks. Fc is being maintained and stable around 4.5 after 9 days. The pucks just ran out with a small residual block still in the chlorinater. Rate of 3 even. Water looks very good however still some very slight algae buildup in corners and steps after being gone and not running vacuum

So ph was STABLE @ 7.6 after two weeks!! So was TA @ 70 even. No MA needed since last adjustments July 2. The FC was a little low at 2ppm with pucks set to 2.5 and no liquid added in over a week due to schedule. Added just enough to today to bring it up to 5-6ppm and added two new pucks as the old ones were depleted. So it appears 2 pucks and a liquid addition lasted two weeks although a slight green algae on steps noted again. Sticking with 2.5 on chlorinator due to summer bathe load and warm water temps as well as lots of rain daily.
Very pleased with ph and TA stabilizing (it appears)! Cya slowly coming up. Scaling seems to be doing better since balancing better with a stabilzed PH and TA level.

After a week with chloriniator at 2, fc was 5ppm even. 2 pucks. Planning to keep 2 on the chlorinator and supplementing with liquid at 1.5 to raise fc to 6.0 target running. That should be just enough balance to keep things level and once cya comes up then no algae during summmer months. That’s as lean as I can run I believe with liquid and pucks. Ph was stable at 7.5 and TA reduced to 70 which is close to perfect. I’d like to continue to monitor to see if ph/TA stays relatively stable. All other levels fine except cya a little low. I’ll supplement with pinch’s stabilizer but I would imagine the pucks are helping raise it slightly. Still seeing some minor green algae as the temp is 88 and we’ve had some rain this week. Also with lower cya levels and only fc 5, tends to allow slight algae to form. I’ll brush and bump chlorine up for the Holliday weekend.

After pcb week trip, returned to ph at 7.6 however TA raised to 90 over the week. Coordinator at 2.5 resulted in FC being 5.5 (11) after testing. Reduced to 2 on the chlorination rate as 2 pucks were consumed in just one week away. Need to run a lower rate yet supplement with liquid more efficiently. Going to add sun coast stabilizer to raise cya level as I think my level is too low for stabilization to take place. I’ve measured 30 but I think it’s actually lower which is why I’m seeing green algae in spots and my ph/TA is still moving slightly.
So reduce TA and PH with Ma. Allow ph to rise up via aeration and stabilizer.
Check FC levels again next Monday (one week) to see if the rate is dialed in. Looking for about 6-7ppm total with pucks and liquid combo. Fast and slow release providing base line. Need to slow down consumption rate of pucks if able.

Today I used MA to lower PH but used too much and it went down to 7.0. Then I raised ph back up to 7.6 via arm and hammer Washing Soda (sodium carbonate not sodium bicarbonate which is baking soda!) It will raise the ph without raising TA which baking soda does.
Added 1/2 L of MA to bring ph back down to 7.3 trying to lower TA from 80 a bit but it didn’t work. TA remains at 80.
I added two pucks at 2.5 rate and the FC rose .5ppm from 3 to 3.5 in about two hours.
I need to add stabilzer from Pinch when it goes on sale next week which will raise my CYA from 30 or 35 to 40 or so. Supposedly this will not effect TA and will help stabilize the ph and TA swing situation. Also will allow the FC to work more efficiently as I’m seeing green algae frequently even after shocking process completed a few days ago.

1L of Muriatic Acid dropped my ph way too much to 7.0! Try half next time to from 8.0 to 7.6! 16ozs equals 1/2 L on MA pitcher.
My strategy is to finally get my ph stabilzed and not constantly rising which is causing scaling. So first I’m going to try slightly raising cya from 30 to 40 ppm. Lowering ph to 7.5 with MA which will also lower TA slightly from 80 to 60. TFP recommends that lower TA’s “should” yield more stabilized ph levels. I’d like to monitor to see if TA @ 60-70 (tested TA after MA addition and it lowered from 80 to 60 as did ph from 8.0 to 7.0 as per amount recommended on this app; thus MA is confirmed to lower TA when needed. ) stabilizes the ph at all. If not I’ll try the other direction and run it slightly higher ie. 90-110 to see if I see ph stabilization. Once I can figure this out then I can focus on the basics of FC, PH, and CSI to keep scaling down and proper balance of ph without constant additions of MA. Trying low first….
Current corrections needed:
1. Need to add Stabilzer (cya conditioner) to raise CYA from 30 to 40ppm.
2. Need to reduce my TA from 80 to 60 target to help with the ph rising constantly. Experiment here between 60-70ppm.
1 year after new plaster the ph will be difficult to control on the high side. Will have to frequently add MA to keep levels around 7.5 to 7.6 target. Should begin to settle down and stabilize after the first year. High ph is causing scaling however with CSI level -.8 to -.9, and high water level, scale will dissolve on it’s own after a few weeks. THEN adjust to maintain CSI of -.3 to 0 and FC=4-6ppm with ph @7.6.
