Per Friday's test, the 100 TA will find its own happy spot as you manage the PH by keeping it in the 7s.

200 CH is fine. Modern fiberglass doesn't need any like it did back in the day. Heater recommendations are outdated too, but we suggest following those (200 CH) so they don't void you warranty.

Your CYA will likely need bumping once the summer UV gets outrageous by you, but is fine for now. Add 10 at a time and road test if you see abnormal daily loss at some point.

Keep FC free and clear above min. It's a moving target and if you need to dose over target range to end with enough FC at the end of the day, that's up to you to recognize you're losing 4ppm in July. (Etc etc). Right now it's probably 1 or 2 lost per day so you can run a lower # and still remain free and clear.

Minimum sounds OK but it's a Defcon 1, all hands on deck situation. Call it Swampville instead and you'll give it the respect it deserves when you find you're 1ppm from Swampville.

In target range is fine. No need to micro-manage to get to some "idea, near perfect" number.

Chlorine is king. pH is second.

When working PH will total alkalinity influence the outcome.

 

[coryg]

Cool. Thanks for all the advice

 

[Newdude]

When working PH will total alkalinity influence the outcome.

TA will affect the dosage amount of MA needed to lower the Ph. Any TA between 60 and 100, or even higher, will manage itself while you manage the Ph.

We only mess with TA if it's particularly high and even then it's usually no rush and can drop on its own.

Tested today and got the following.
FC=.6 ppm
CC=.2 ppm
PH=7.8
TA=140ppm
CH=170ppm
CYA=30ppm

Numbers are driving me crazy, added 182 oz of 10% bleach as per pool math.
Dropped a sock of stabilizer in the water to try to get to 40ppm.
Need and will get acid tomorrow. Only thing, pool math doesn’t give the required amount to get in ideal range.

Y’all got any helpful hints?

Ideal range for PH is anything in the 7’s. If you’re working to drop your TA, then adjusting from 7.8 to 7.2 would be in order and readjusting once is rises to 7.8 again. The dose amount for your desired change will vary based on your TA level and MA strength (borates also play a role but you don't have any from memory so it’s nothing to worry about). Assuming you get full strength acid (31.45%), at your current TA of 140 you would need 56 oz to drop from 7.8 to 7.2.

Thank you for the help. I will get the acid tomorrow. Is there any other recommendations as per the results from the test?

Your FC is way under for your CYA level. You’re inviting a swamp. You want to target between 4-6 ppm FC, with absolute minimum being 2 ppm - or you’re staring a swamp in the eye. Add chlorine asap.

 

[Newdude]

You want to target between 4-6 ppm FC, with absolute minimum being 2 ppm - or you’re staring a swamp in the eye.

+1. And the 4-6 range isn't inherently acceptable. That's a round about guess for your winter target losing 1 to 2 ppm a day, and your summer target losing 4ppm a day.

You have to understand your recent loss to set the target for that part of the season.

If you find you're losing 5ppm mid summer because Louisiana, then you need to dose over target to remain free and clear above min at the end of the day. Many of us dose over target all year, to land mid target after the daily loss in the summer, or not have to pay attention for days when it's cold out.

At all times, you want:

Min FC
+ recent daily loss
+ 1 or 2 insurance FC
------------------------------------
= stupid clear Trouble Free Pool.

Also you are blowing through 2.5X the supplies testing with a 25ml sample for FC. Use 10ml and each drop is .5 FC. The '0 point something' sucks because of the 0. Whether it's a .6 or a .2 means nothing.

Conversely, a 8.2 and a 8.6 are both awesome for most CYA levels. There is simply no need for .2 resolution.

I dosed yesterday to reach a level of 5 ppm. I will retest this evening and bring to a level of 8. And retest tomorrow to see daily loss.

Did I miss the part where you passed all 3 end of slam criteria?
You are done when:

CC is 0.5 or lower;
You pass an Overnight Chlorine Loss Test
AND
The water is clear.
(Crystal Clear w/no algae dead or alive)

Its seems you have moved on to other things before fully completing the
SLAM Process
While fc is below 10ppm it is ok to adjust ph to 7.2 but then just keep with the slam only testing & replenishing fc to slam level multiple times per day until you meet ALL 3 end of slam criteria.
You added more cya so now you have increased the necessary slam fc level.

 

[Lake Placid]

Your TA has jumped from 100 to 140 since Friday? Did you add anything that would increase TA. That’s a large variance. If you haven’t added anything, retest TA for certainty before adding MA.

I did not do the slam method. I can only answer two of the three questions. Water is clear and CC is lower than .5. I would have to check on the OCLT test and how to do it.

Only thing I added besides stabilizer and liquid chlorine was pot ash.

Do you mean soda ash? Why?

Yes that’s what meant. Brain is moosh from work. Was following pool math app

Your numbers were fine- your ph would have risen on its own with a ta of 100.
No need for soda ash.
Now your ph will rise even faster since you increased your ta to 140 with the soda ash.
No worries- now you know.
Ph in the 7’s is fine.
If your water was cloudy you should focus on fully completing the
SLAM Process before doing much else.
Bare minimum- do the
Overnight Chlorine Loss Test at target level fc

Ok. I was totally off. I just used search function and figured out what OCLT was. Will do it tomorrow. I raised my FC to 8.3 tonight (my pool math app, not tested).

I really thought that was a test for algae count
