Houston, TX No-Shade Pool Owners, how much FC loss

It's not just the algae, which somehow always finds a way, but bacteria and all the other nasties. You want freshly chlorinated water circulated once a day for 15 mins if they aren't being used on their own.

Ugg. Turned on spa and blower. Somethin ain’t right…

Spa blower allows air to be sucked in when off
Ok, so… i turned my spa on (heater off) just to circulate freshly chlorinated water thru the spa related pipes. All good. Then I turn on the blower for a minute just to evacuate the blower related pipes of any old water so that when I turn the blower off, freshly chlorinated water enters those...

Mason and Highland Knolls checking in, losing 5ppm a day. CYA currently at 60. Switched to using chlorine tabs to up my CYA. Also added a 20x16 sail shade to cover half the pool.

I wanted to post on this thread to provide some follow up on my own high levels of daytime loss.
Bottom line, I was testing for CYA incorrectly. I thought I understood the process but it took a visit to the Wiki to really understand how subjective this test can be if you are not careful. I had markedly overestimated how much CYA was actually in my pool water-- thought I had over 50 but I actually had level well under 40. I have since brought my CYA levels to above 50 ppm and I have seen daily loss much closer to 2-3 ppm.

What exactly were you doing wrong? I’m pretty I’m doing it right, I’ve read a zillion threads on how to test CYA. Sun at back tube at waist level only a glance etc etc
Last year I tried a few ways but this year I did my tests outside in the shade (gazebo) on a piece of paper on my table. My pool receives direct sunlight from 7am til 3pm and non-direct from 6pm-~8ish. I leave my cover on unless I'm going in or cleaning (3-4 times a week manually) and I loose ~1ppm daily. I add 35oz lc on Monday and Thursday nights. Been working amazing for me. Opened my pool 3rd week of May, initial slam, haven't used 20 gallons of lc yet and that is all I use. I don't have any other chlorinating products.
At best, if you do everything perfect, it's still subjective. We don't all see an eye chart or colors the same either. So maybe you are less compatable with the test than others.
Who else can you enlist to try?
If that still didn't change anything, I would personally rely on the FC loss and raise it 10, possibly even another 10 if that didn't hold either.
*assuming a current OCLT pass. A couple of days ago / last week no longer counts as many things could have happened since then.

I think the simplest way to describe my issue was doubting I was seeing the dot when it was actually somewhat visible, as a result of blurriness at waist level that could not be addressed well by my regular reading glasses. I would bring the vial closer to my eyes but then try to compensate for stuff being visible that might not be at waist level.
Once I got presctiption glasses designed specifically for intermediate distance (like the computer work ones but without the blue filter) and did the test I realized how overly conservative I was being.

I've only tried my test outside once. Full sun with back to shade. The challenge I found was that I can see my little head against a bright blue sky reflecting off the surface of the liquid in the tube. Awfully hard to distinguish my head from the Black Dot of Happiness.
Pinch a Penny. The bottle says 10.5% on it. When I called PAP before I started getting Lc, I asked a few questions. The guy told me they purchase it at 12.5% but they only advertise it as 10.5% because that’s what they can guarantee. But he told me it actually move very quickly once they receive it. For what it’s worth I use 12.5% for my pool math input and it’s always on point.
You have to buy the container the first time; it’s like 7 or 8 bucks. Then you just swap them out when empty for full ones. Looks like they are 10% off now. And after you buy 10, the 11th jug is free.

Pinch-a-Penny chlorine also moves quickly here in South Florida so it's always fresh. Measures consistently above 12% concentration on day of purchase.

I dilute a sample 10000 to 1 and test dilution for ppm. Learned the technique here in fact!
Dude they just jacked up the price again uggggg! $13 for 2.5 gal before tax. Was $11 and change just several weeks ago…AFTER tax.

Woah that's still pretty good. Up here in Dallas, I called and was told it cost $18 for 2.5 gallons.
