Pump is running 24/7 at 1500rpm. Filter pressure has gone up 1-1.5psi. I tested for a lot of things and there isn't much. Iron is 0.02, which is way under 0.3ppm that should cause issues. And it went from fine to this overnight. I can see the bottom on the shallow end (3.5'), but can't see the...

Checked at 3pm and it was 14.5, so whether algae or sun, FC has gone down at least.

I tested yesterday at 5pm when I noticed it was green and dosed to 18ppm, then 6ppm it was really 19.5, then 7pm it was 21, then 10:30pm it was 18, then today at 7:30am it was 17.5, then 10:30am it was 17.5. I have not added since 5pm yesterday because the FC has not dropped below the SLAM value.

I just vacuumed after a week and it looks completely normal. Some leaves and dirt. Checked FC again 3 hours lately, still 17.5, so in 12 hours it's only gone down 0.5. Here's a pic of the area where the main drain is, I can't see it at all though. 2 days ago you could see the screws.

I did a full test 7/27 after adjusting everything, but can redo if needed. FC-17.5 from this morning CC-0 from this morning pH-7.2 by calculation after measuring 7.8 yesterday TA - 90 (7/27) a little lower with new acid addition CH - 450 (7/27) CYA - 40 (7/27)

I just fill the view tube to a line, then glance at waist level. If you see it, add water to the next line, then glance again until you don't quickly and confidently see the dot. The scale is non-linear, so between lines on the tube don't matter. Staring at it and adding a few drops at a time...

I have more things that don't make sense. This is algae right? I added chlorine to SLAM level at 5pm last night and was prepared to add every hour. At 6pm, it was a little higher than calculated, at 7pm, it was even higher than that. I tested at 10:30pm and it went down 3ppm to 18. I just tested...

I do leave a solar cover on most weekdays. Maybe that is the issue, affecting circulation and CC oxidation. I run my pump 10 hours/day currently. Should I open the pool every other day at least, or something like that? I brush what the robot can't reach and let it vacuum 1-2 times a week. With...

This is my first year with the pool, but I have kept up with chlorine. Opened the pool today to add chlorine to be surprised by cloudy green water. I just tested and got FC-5, CC-0. CYA is 40, pH 7.8. Is there anyway I could get algae with my FC never dropping below minimum? I'm guessing I have...

I got mine installed no problem, even though it is a huge breaker. Haven't had any trips yet.

Yep, that's exactly what I was going to build to hook to the sump pump.

I figured I would update. I got a $50 sump pump and ran it with garden hoses to exchange water. I ran it for 36 hours the first time and got the CYA from ~120-160ish down to 70. I ran it for another 22 hours after that and it's in between 40-50 now, which I'm fine with. New test results: pH -...

Ok, I just don't want to run into scaling issues. I am draining 2/3 of my water now to resolve high CYA and will have to add Ca to get the hardness up to whatever the goal is.

Previous posts and the wiki say 250-350ppm for a plaster pool without SWG. The new pool school recommendations are 350-550ppm, which is a huge difference. Which level is correct, or why did the recommendation go up so much?

We're at 2000ft, but we do have 2 lakes, a river, and creek within 10 miles, so it's probably not worth risking. I'll just exchange until CYA is low enough.
