Water balance frustration

[TeachO]

The data you have entered is not from a Taylor drop test kit. What did you use?

Here are today’s test results using the pool math app. Still green but FC keeps rising.

You are likely correct - my apologies. But TA should not be tested like that as it is much to inaccurate

Okay - to clear the green/cloudy pool you need to do the
SLAM Process.
Your fc is currently not high - Slam fc level for your cya of 60 is 24ppm
(there’s no inbetweens on the cya test - always round up if the dot disappears between two values)
Your ta (which is only measured in increments of 10 - no extrapolations) has been increasing (are you adding something to increase it? If so stop
As mentioned, please use
PoolMath as it uses tfp recommended levels, & suggestions, doesn’t “adjust” ta & also lists fc & cc separately which is very important.
It is free to use & will help you calculate all additions accurately. If you wish to retain more than 1 log for your records there is a yearly subscription fee of $7.99.
Its very important for you to have a fairly accurate volume estimate of your pool so you dose accurately.
At the bottom of this Page there’s a calculator for that

Thank you. So I need to add more chlorine/bleach to get to 24. Not adding anything to increase TA. I paid for the subscription for pool math as well. I want to figure this out!

I just updated. using a rebranded k-2006

Your test data now shows you at a CYA of 40. How did it drop from 60?

I wish I knew. We only added chlorine last night

 

[mknauss]

OK. I know the CYA test is difficult. But realize the only way to actually change the level quickly is to drain the pool. I doubt you drained 33% of your pool volume.
If you are going to use the 40 CYA, then your SLAM level is 16 ppm FC. Maintain that as often as you can. Be sure you have read the SLAM Process

ReDo the cya test so you can be sure you’re using the proper amount of fc
(outdoors on a sunny day is best) doing it in different lighting conditions will give different results- you want to be consistent.
here’s the full directions :

CYA - Cyanuric Acid Test

Cyanuric acid (CYA) is the chemical name for the product commonly called “pool water stabilizer” … Read more…

I followed your instructions and the CYA tested at 50.

 

[TeachO]

I followed your instructions and the CYA tested at 50. my FV was 16

My FC was at 16 today

I followed your instructions and the CYA tested at 50.

So you want to maintain fc of 20ppm

FC/CYA Levels

For a successful SLAM Process
you need to continue to MAINTAIN Slam level fc for your cya as often as possible (multiple times per day is best) until you meet 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)

*Check & scrub every nook & cranny where algae may hide (light niches, steps, drain covers, ladder handrails, skimmer throats/weirs, abandoned lines, autofill, overflow drains, etc.)
*If water can go there, algae can thrive there.
*Run slam level water through all water features & lines for at least a couple hours a day during the SLAM Process.
*Brush & or vac daily (this breaks up biofilms that algae uses to protect itself from chlorine)
*Backwash/clean filter when pressure rises 25%over clean pressure.

I’ve followed all your advice. My water is not green anymore but is still very cloudy, almost milky-like. Can’t see the bottom. These were the results today.

 

[mknauss]

You need to continue the SLAM Process to completion.

Keep at it- replenishing fc to slam level multiple times per day. Be careful with using cal hypo- too little ch isn’t much of an issue with a fiberglass pool but too much ch will cause scaling problems.
Large additions of cal hypo can also contribute to cloudiness.
Liquid chlorine is best.
