Re: New Test Results after heavy rain.

There really isn't any adjustments needed, just let the FC fall back down on its own. The pH is not considered to be accurate due to the FC being above 10. Usually rains do not affect the chemical readings by much as the added water is still a small percentage of the overall water in your 15K gallon pool.

Re: New Test Results after heavy rain.

Are you slamming? or what is the story here?

I merged the threads to keep the story together.

Re: New Test Results after heavy rain.

I accidently added too much bleach, here is the latest test results

FC - 16
CC- .5
PH - 7.8
TA - 130
CH - 200
CYA 60

 

[jblizzle]

No you did not. With a CYA of 60ppm, shock level is 24ppm.
Although at this point I have no idea what you are intending to do.

There is also no way your CYA dropped from 80 to 60ppm unless you replaced 25% of your water.

 

[sgosine577]

Now learning, I figure the only adjustment is to bring the TA down to 100 ppm and PH down to 7.6 ppm after I get the FC down to 5 ppm
I will wait about 3 days before i do another test to see if the FC comes down.

Yes I replaced 25 percent of the pool water and it rained heavy for 2 days.

 

[jblizzle]

Hold on.
Forget the TA and the FC only has to be less than 10ppm to get a good pH reading.

You better not wait 3 days as it could be too low by then.

 

[sgosine577]

OK I will test it tomorrow

 

[sgosine577]

Latest test results 1 May 2015 Need to bring TA and PH down 1.5 qt of acid and and aerate to bring PH up, and maintain Fc at 6 PPM at 60 CYA. Also increase CH.

FC 6.5

CC .5

PH 7.9

TA 120

CH 200

CYA 60

 

[jblizzle]

Forget the TA, just keep the pH in range.

 

[sgosine577]

Test results 2 May 2015, Added 32 ounces of MA, 26 ounces of 8.5 percent bleach, and added 1 pound of CH, Did drain 8% water.

CL 5.5
CC - .5
PH - 7.6
TA - 120
CH - 240
CYA - 55

Will add 26 ounces of MA to bring PH to 7.2 this will reduce the Ta, then aerate to bring up the PH, Will add 32 ounces of calcium to increase CH. What do you think Pool is clear and blue.

 

[pooldv]

That is a good plan! Numbers are looking good. Were you slamming before? I was never clear on that. Did you pass overnight chlorine loss?

 

[sgosine577]

yes I was slamming, turned green pool to clear and blue, took 2 weeks, pass overnight cl loss

Test Result 3 May 2015

FC 3.5

CC 0

PH 8

TA 90

CH 270

CYA 60

ADDED 1.43 QT MA to adjust PH to 7.2 PPm, ADDED 42 OZ 8.5 BLEACH to increase FC to 6 PPM

 

[pooldv]

Numbers are looking pretty good. Except you are running a little low on FC. The Chlorine CYA Chart says that for 60 cya the min FC is 5 and target is 7. That means FC should never fall below 5 or you risk algae growth.

 

[sgosine577]

TEST 4 May 2015

FC - 5

CC 0

PH 7.6 ADDED 1 QT OF MA TO BRING DOWN TO 7.4

TA 90

CH 270

CYA 50 measured after heavy rain dump excess water

finally getting the pool perfect. Water is blue and clear

 

[pooldv]

Sweet!

 

[sgosine577]

I love it when a plan comes together, thanks guys!

 

[sgosine577]

Tested 11 May 2015

FC 4

CC .5

PH 7.6 ADDED 1\QT ma

AL 70 ADDED 57 OZ OF BAKING SODA TO BRING THE AL TO 90

CH 270 WILL BRING THAT UP TO 300 LATER

CYA 50

ADDING BAKING SODA BRINGS THE TA UP BUT ADDING MA BRINGS IT DOWN. I GUESS I WILL BRING THE PH TO 7.0 AND LET THE WATER FALL INCREASE THE PH, AND INCREASE THE TA SLOWLY.

 

[jblizzle]

Please do not type in all caps ... it is considered shouting.

A TA of 70ppm is fine. No need to raise it ... and adding baking soda does VERY little to the pH.

Of more concern is your FC being at the minimum for your CYA ... you need to get that FC up.
