Sorry for the long delay; a lot going on the past month. It is getting cool here, so just trying to clear up the pool and cover it (lately only running pump 10hrs/day). All of whatever the recent green cloudiness is has settled out to the bottom. The rest of the pool water is crystal clear...

What is a good pH to maintain knowing I have iron in the water? Is it still 7.2 to 7.8 or should I try to maintain it closer to a specific value?

We do have iron bacteria in the well water, but I would expect the iron to be brown, like it was when we filled the pool, not green. We used the clean, clear pool for two weeks, until we got the first rain and I noticed the green. I'm getting better at responding to problems. This week, the...

I do not do an OCLT every day if I have already passed the 3 SLAM tests. Also, the previous day before the rain, the OCLT did not drop - 11.5 at 9pm and 11.5 at 8am). So, then I only do an AM Chlorine check and hence, do not know what the OCLT would have been after the rain and once the green...

I think I may have misunderstood your last question. After I had a clear pool, the FC had been running consecutively at 12.5 (8am), 11.5 (9pm), 11.5 (8am), then next day at 8am it was 10 after an overnight rain and that morning is when I saw the slight green tinge on the walls. Today and...

I will test tonight and again tomorrow morning and post an update.

Recently when seeing the green, I brush all the walls and floor and bring the chlorine up immediately and notice that the green turns white. Once it is white, I have very little loss overnight - maybe 1 - 2ppm.

It is above ground completely from bottom to top. There is no cover over the pool area, so when it rains, it gets rain water in it. The surrounding trees are not directly over the pool, but with a breeze, we get pine needles and other leaves into which it I clean out daily - sometimes multiple...

Thanks, ajw22. Here are my responses. Q: After a rain when you first see algae what is your FC level? A: As noted, FC has not even dropped back to normal limits, yet. Still above 10. In second paragraph, it was 12.5. Q: Do you add liquid chlorine daily? What time of day do you test and add...

Hi, all. I let FC get away from me and found it low or 0 once or twice and then developed moderately green pool (4600 gal, above ground). Results at that time (TF-100 kit): pH 7.2 FC 2.5 CC 0.5 Alk 240 Hardness 525 (no control, it comes from the well that way) CYA 30 My CYA was 30, so I...
