Can't fight City Hall! Do what you gotta do.
However, "runny poo" is not a symptom of chlorine over exposure.
In your last post, you mention opening cloudy, but earlier you'd mentioned cloudy in the AM -- different, unrelated problems. Which are you trying to solve? Cloudy in the spring, or cloudy in the morning? I thought it was the latter; if it's the former, we've been on the wrong track.
Regarding your chlorine demand -- if you have heavy lotion load (and it sounds like you do) and you have frequent peeing in the pool (and I suspect you do), 5 ppm loss per day is not surprising, so the PM to AM drop may be normal for you, and your pool.
If your pool is clear now, go ahead and let it drop (as if you have a choice), but stop the drop at 15, and then hold the 8 - 15 ppm level you need for 100 ppm CYA. If that's intolerable to City Hall, you'll have to drain and refill till you get your CYA down to 40 ppm or so.
BTW, I'm 99% sure your poo issues have nothing at all to do with your pool issues. But, as I have always told my commercial customers here, even when the health inspector is wrong, they are still the inspector, so if we can we go along!

Now im confused. Every spring ive open to a couldy milky pool. Then if i ever let my FC drop to near 0 I would wake up to a cloudy pool. I assumed my high CYA as been allowing algae blooms to go on for years. Now you want me to drop my FC. I still cant maintain my FC overnight. I dont want to stop shocking until thats accomplished unless you recommend it. Ive spent alot of money on bleach so far. Its very hot now so I cant drain now. i plan on doing it this fall. Thank you very much for replying. By the way my wife will have to suck it up since ive gone this far
Hi Shub;
Different strokes, and all that. For some of our users once the wife lays down the law, the discussion's over.
OK, you've added a bit of information I didn't have before (maybe I overlooked it?). Anyhow, it is ABSOLUTELY NORMAL for a pool that's being used regularly to get cloudy overnight if the chlorine drops to zero the preceding day, ESPECIALLY when you have heavy lotion users, using the pool. To prevent that, you MUST keep the chlorine above the minimum level shown in the Best Guess chart -- if you haven't read that page, you really should do so -- for YOUR CYA level, whatever it is.
Currently, with your CYA at 100, that means the MINIMUM allowable level is 8 ppm.
Without considering your wife's preference, here's what I would recommend you do:
+ Hold your current levels for 2 days AFTER the last trace of any algae. (You may already be past that.)
+ Once you've gone 2 days with NO algae, and no slipperiness on the sidewalls, let the chlorine drop to 10 ppm.
+ When the chlorine drops to 8 - 10 ppm, add 2 gallons of plain 6% bleach that evening. Test chlorine daily (for now) and repeat the 2 gallon dose in the evening of each day you see a level below 10 ppm FC.
+ Meanwhile, use muriatic acid to drop your pH to just below 7.0. Let it rise to 7.4 (it will); repeat the acid dose when it reaches 7.4. This will gradually lower your TA.
+ If you want to do so, you can ALSO raise the borate (borax) level in your pool to 60 ppm or so. This will make your pool more resistant to algae, but NOT to lotion / urine / body oil based cloudiness. Let me know if you want to do so -- it will take 16 boxes of 20 mule team borax and around 4 gallons of muriatic acid if you want to do this.
+ Do what you can to eliminate peeing in the pool - for a lot of boys, it's as simple as giving them permission to "pee behind that bush over there"! Urine really does use up a lot of chlorine.

past steps 1 and 2
If i havent killed the invisable algae problem will i get another bloom quick if i drop below 10ppm, say 5 by accident
I dumped 4gl of acid now to begin aerating.
Havent lowered yet so no added borax
Do i need additional acid and borax to increase borates after im done aerating and returned normal to PH
Hope i dont sound like too much of an idiot. I stress alot over the pool. And am impatient. Thanks for your help
It's certainly possible. Usually, when people drop below what they should, they get lower than they think, for longer than they think. What I've told my commercial customers for years, that if the chlorine gets below 0.5 ppm (on pools with CYA=30), the pool WILL be cloudy the next day. Usually, it is.
In warm weather, pools need to be EFFECTIVELY chlorinated 100% of the time; not 95% or even 99% of the time.
Use the dilution with distilled water method to check your pH NOW!!I dumped 4gl of acid now to begin aerating.
You do NOT want to get below 6.0 at ALL. It WILL damage your liner. If it is low, go get 10 boxes or so of borax, and add 2 to start, and then 1 every hour till you get back up above 7.0. (You have to go above 7 because your kit can't distinguish 6.8 from 5.8!)
Yes. Acid use to lower pH from borax is separate from acid use to lower TA. However, any borax you've added this season for ANY purpose counts toward the total.Do i need additional acid and borax to increase borates after im done aerating and returned normal to PH
Nah, pretty much normal for a nervous pool owner.Hope i don't sound like too much of an idiot. I stress a lot over the pool. And am impatient. Thanks for your help

Only some you say? What's wrong with the rest of them?? I can't figure that one out!
Shub --- never add a big dose of anything at one time -- except bleach when you are shocking the pool. Of everything else, it is always better to use smaller doses and gradually get to targets than risk overshooting them.
Snort!
Ok. Added 1 1/2 box of borax. Took ph to 7.0. Still aerating with 50ppm reduction in TA based on 250ppm earlier. Pretty much no sun today, sum, 91F. Check FF with dilution and appears to be 28-30ppm. It may be holding. Crossing fingers.
