For simple test kit, 12 ppm still looked orange, while 10 ppm looks dark yellow. So, one could estimate that going 1 additional day before adding Cl 1-2 ppm, would be sufficient. Let's see ...

Sun was up but not shining on pool yet. Took two different samples and measured each twice ...

Circulate 30 min: 37 (18.5 FC), 37 (18.5 FC)
Average: 18.1
Drop size or amount of DPD powder or both? "One heaping scoop" is less predictable than "two level scoops" as advised by Taylor. I did observe variations in the size of the drops. 5 drops difference?
Either way, we have one reasonable (<= prev night) reading at 16.5, which is ONLT of 1.0.

Advice was to use 1 heaping dose of DPD powder, and then let drips fall naturally from the bottle without squeezing, and swirling tube constantly.
Did all but the natural drips ... nothing was dripping out without a little encouragement.
So, each drip I went through the whole cycle of uprighting the bottle, turning over to full inverted position, and applying slight pressure to encourage the drip to form. Then swirl tube while resetting the bottle.
At least now 17.5 is <= 21.0 from last night (correct or not, at least it's reasonable).

Sample taken from mid-depth with pump off overnight and some amount of overnight rain. Similar drastic difference between evening and morning tests, except the opposite of a couple days ago (high out of expected level in the evening and back to expected level in the morning... today the opposite).
All new DPD chems in the past week, so it should be consistent measurement recently. New R-0003 for CC testing today, so maybe better detection than prior tests with older chem.
Pump just started at 8am. Will test again in 30 min. Cloudy and sprinkling this morning, so hopefully not too much affect on ONLT attempt.

Much clearer this morning than yesterday... SLAM an extra day or more if you think you're clean.
Possibly affected by heavy rain... but super clear is more than clean when you see it.
Not sure about ONLT ... was surprised when last night's reading was "so high" ... so possibly a miss count or some ghost drops (a bubble instead of a full drop... patience needed to fully reset bottle between each drop to get a correct drop). This morning's reading is closer to expected ... but alas not conclusive with a 6ppm FC difference.

TFP Forum thread says that SLAM Process is the response to take when algae initially forms.
Before that, the correct balance of FC and CYA needs to be maintained to prevent algae. The higher the CYA, the higher the sustained FC level needs to be (see chart). Recommendation is to sustain at the high end of the PoolMath app target range. For CYA of 60-70, that would be 9-10 ppm (vs the 4-5 dipping to 3 trend shown in my test readings).

Adding 3.5ppm, to approx 8ppm.
With no or little CC, I don't need a high breaking point, but the CYA buffer also makes Cl approx half effective. So, 3ppm x 2 plus some wiggle room ... is 8ppm.
I know, slam would be 24ppm at this point, so 8ppm may fall behind or take longer to clarify... but I'm not willing to go without swimming for this week's highs.

Finally figured out that there is a black blog reflection from outside the tube (possibly my black hair) that obscures the marker itself! If I tilt the tube around slightly, I can see that false blob move around while observing the actual marker (or not) at the bottom. Much more confident now about the reading process.
Water looks a little hazy, but FC consumption since yesterday was only 1.5.

FC reading this time was the 25ml sample vs 10ml. I had noticed some variation in the 10ml sample results, so decided to use the more precise measurement. Not sure what's happening.
Took this sample from 2ft left of skimmer, where prior samples were taken from across the pool. I don't think that the concentration of new Cl from the SWG located 2ft right of skimmer (4 ft away) is that strong ... but will return to the distant sample location next time to minimize variables.
Also, realized yesterday that the CL instructions say to use 2 dippers of powder instead of 1, which I believe I had been using all the time earlier in the year. I don't know if the amount of powder used affects the results, or if it is only necessary to see the solid pink color before starting the measurement drops. The instructions say to add more if the color doesn't change to pink, so that implies a variability that does not affect the reading.

Hasn't rained for several weeks. Pool has been relatively stable. Brushed a few times (not recorded) and vacuumed once a week (not recorded). Noticing a few spots of green dust on bottom that fluff away when disturbed. No slippery spots.

Water is clear this morning. Vacuum didn't disturb much, so water remains mostly clear.
Decided not to run SWG after Noon as Cl is above slam target. Will start normal filter timing and do an ONLT tonight.
Not sure what's up with CYA. Air temp is a little warmer today. Hand-warmed for a similar amount of time both days.
pH is going up on it's own.

Had observed high pressure @20 but flow seemed good. Part way through vacuum session, the filter clogged. Very low flow discovered near end.
Observed some areas where white clouds of dust were kicked up in front of vacuum head. Not sure if that was debrit or undissolved salt.
Backwashed (significant white foam) restored flow and pressure @14.
Some cleanup vacuum afterwards.

Test and SWG agree on salt level @ 2900-3000.
CYA levels are increasing slowly using 1 white sock full (3/4 lb.) at a time in front of the return jet. Hopefully by later today we'll get a first measurable level.
Water temp is 71.
Slightly cloudy. ONLT with filter running (no SWG) shows a drop of 3.5.

Yesterday, heavy rain continued. Today, skimmer is nearly covered by water, but a small gap remains. Will drain some later.
Observed a small patch, quarter sized, of green algae forming. Added 16 oz. bleach to try to get ahead of it today. Will take chem readings later as well.
