    pH: How high is too high?

    OK. Scale formation: if my CSI is OK? / Skin: not currently swim season. / Seems there is some difference of opinion on HOCL/OCL significance. What else? Thanks to all for chiming in.

    pH: How high is too high?

    Thank you all. The CSI is nominal, the salt is just accumulated over the years, and, you're right: I should either buy a pH meter or just add some acid! BTW, what exactly is bad about having a pool pH in the 8s? Ron

    pH: How high is too high?

    Greetings. I've asked this years back, but now I'm into uncharted high pH territory and I want some opinions. As you'll see, my CSI is fine. And I figure, if I don't have to go out in the cold and add acid, I won't. I'm lazy. Thanks. pH 8.5 (approx. as 8.2 is top of the color scale) FC 5.5 TA...

    Big time daily chlorine loss

    Thank you all. You are correct. My CYA is below 30, above 20! Adding now. Sometimes it seems I have to pose the question before I can do what is really needed to solve it. Regards,

    Big time daily chlorine loss

    Today: FC 0.5 CC 0.5 pH 8.0 CYA 40 (last checked 3 weeks ago) TA 110 CH 175 Salt 2400 (last checked 6 months ago) Borate 40 (last checked 6 months ago) I use the TFTest kit.

    Big time daily chlorine loss

    Greetings. I have always noticed a large daily drop in FC during the summer. Up to 5 points is not uncommon for my pool. However, it seems to be even more lately. I target FC at 7.0 every morning. This morning's reading, pre-chlorine addition, was 0.5 points. 6.5 point loss during the day? Wow...

    Has "old" Pool Math web page been replaced?

    Cool. Thanks for all you do.

    Has "old" Pool Math web page been replaced?

    Thanks. I guess I can just keep in mind some of the target ranges that seem to have been re-jiggered. The basic chemistry calculations remain the same.

    Has "old" Pool Math web page been replaced?

    Is the web based Pool Math still OK to use?

    Has "old" Pool Math web page been replaced?

    Hi. I don't have a smartphone and use my Apple desktop and laptop to run Pool Math web page. Is this still current? I'm seeing info. about an app with updated suggested chemical levels. Thanks.

    First FAS-DPD chlorine often way too low

    Yes. / I just had a thought. Maybe letting the first drop of R-0871 go to waste? Perhaps it concentrates in the tip while stored overnight?

    First FAS-DPD chlorine often way too low

    A puzzler: My first attempt at FAS-DPD often gives me a ludicrously low FC. Then I wash and refill minutes later and voila! I get "the result I want". Same water, everything. Example: today's first FC was 2.5, CC 1.5. Then FC 4.5, CC 0.5, then FC 4.0, CC 0.5. This happens 50% of the time. Anyone...

    pH: how high is too high?

    CSI according to Poolmath is 0.19. Scale will not occur, but does pH 8.3 begin to have a degrading effect on pool plumbing, pump interiors, etc.? Perhaps I should add that no one is swimming in this pool until spring returns.

    pH: how high is too high?

    Greetings, fellow travelers and pool owners. So my CSI is still fine with pH 8.3. But how high is too high as regards pH's effect on the pool's infrastructure? Thank you. Today's readings: FC 5.5 TA 100 CH 200 CYA 30 Temp 62 Salt (from 9/19) 2400 Borate (from 9/19) 40

    Always amazed how much chlorine full sun sucks up

    Thank you. I have ordered a 25 lb. box CYA and I will bring CYA up to 50 and see how I do.

    Always amazed how much chlorine full sun sucks up

    Thanks. How does higher CYA keep one from losing as much FC daily. I'll have a higher target FC, but you say I will lose less per day and save on chlorine cost?

    Always amazed how much chlorine full sun sucks up

    Low 30's. I use 40 to base FC target. Water temp 84.

    Always amazed how much chlorine full sun sucks up

    Every year I go through my early season dis-belief at how much my FC goes down every day. Right now it seems to go from 6 to 2 (or lower) every full sun day. The house is on the east side of the pool and large trees on west but for at least 8 hours the sun hits pool directly. I am now onto a new...

    free Phenol Red R-1003J

    Somehow the color is slightly different. I think I checked and the pH of the dye solution is different. I ran a little experiment at home with the right stuff and the wrong one and could never get any kind of consistent correlation.

    How often to add more borates?

    Borate seems to persist very well. I test a few times/year and add boric acid no more than yearly, perhaps less.

    free Phenol Red R-1003J

    I inadvertently purchased Taylor pH Indicator Solution (Phenol Red) R-1003J, C Size: 60 ml (2 oz), expires 02/19. After experimenting with it and determining I could not use it, there remains approx. 2/3 bottle. If you want to split shipping cost, its yours. Thanks and regards to all TFPers.

    Can I use R-1003J for TFT-100 comparator?

    Seems I bought a 2 oz bottle of R-1003J for refill. Can I use this in TFT-100 test kit comparator? Thanks.

    Does a higher CYA in summer have advantages?

    Once you have bumped up to new target FC, you will only be replacing daily loss, which supposedly is less (?).

    Does a higher CYA in summer have advantages?

    Thanks. I had focused on a different graph but I see your point. Plus I read further in the deep thread that chem geek refers to as-yet unexplained empirical data that chlorine loss does lessen at higher CYA. I shall raise my CYA to 50 and join the club.

    Does a higher CYA in summer have advantages?

    That was a seriously deep thread. I was submerged for a long time and just came up for air. There was a graph that I think you were referring to showing chlorine loss/hr at varying CYA and chlorine ion levels. I still don't clearly see the advantage of a higher summer CYA.

    Does a higher CYA in summer have advantages?

    Greetings. I seem to understand that raising my CYA for summer full sun will be an advantage. I am currently CYA 40 and lose 3 - 3.5 FC daily. If I move CYA to 50 or 60, will my daily expense of chlorine go down? Thank you. pH 7.7 FC 6.0 CC 0.5 TA 120 CH 250 Borate 40 CYA </= 40 Water Temp 82F

    What were you doing before TFP?

    I was a pool store victim. At one point I had to hire a pool guy with 2 portable DE filters to de-swampify my pool in 2 days so visiting out-of-town friends would not be horrified.

    Invalid Redirect??

    Does anyone know why I get Invalid Redirect first time I login, and then when I enter info again it goes through and logs me in? I use Firefox. A minor inconvenience. Thank you.
