So confused.

I imagine. With that high TA it would be tough to manage. The CH is not as big a deal.

Your best bet is to force the TA down to 80 ppm or less and then use enough acid every other day or so to keep the TA down.

Will be less of an issue during non-swim season as it is all tied to evaporation.

 

[mknauss]

TA and CH have nothing to do to being able to swim. That is FC and pH.

Follow the SLAM Process. Read the article.

Ok thank you.

I added muruatic acid to bring down the PH before I SLAM. How long should I wait to retest?

 

[mknauss]

Pump running for 30 minutes is enough.

PH is 7.6 (yay)
CYA is 34
The chart says about 15. But I’m not sure what measurement that relates to?? ?

 

[mknauss]

Add enough acid to get to 7.2. No need to test again.

Use CYA of 40. You cannot measure a 34, the vial is logarithmic.

SLAM FC of 16 ppm. Raise your FC to that level. Test FC every couple hours if possible and add liquid chlorine to reach 16 ppm.

Ignore that, I found the chart.

Thanks so much for your help. I will re test again in the morning and hope for some positive results!!

You realize this is a process, right? You need to be testing FC as often as possible, no less than 3 or 4 times per day, adding liquid chlorine to get back to SLAM level FC each time. Only test FC. No other tests matter right now.

Yes sir, I just tested again, actually have a reading of free chlorine, and added the recommended amount of bleach. Thanks for clarifying it all for me, it’s just a little confusing knowing what to do first! And I’m up for whatever you guys think you need to tell me!

 

[Flynnranch]

So I messed up and did not check the SLAM box on the APP to begin with , hoping I am on track now. If someone could take a look at my logs I would sure appreciate it!

 

[mknauss]

It does not appear to me you are adding sufficient liquid chlorine to reach 16 ppm FC, your SLAM Level based on 40 ppm CYA.

I just tested the CYA again, and the black dot never did disappear.

 

[mknauss]

CYA level does not change rapidly unless you drain water.

When you do the CYA test, try this next time.

Once you have your solution ready, back to the sun, etc. Fill the vial to a line, say 80, lower the vial to your waist level and glance for the dot, you see it, add solution to the 70 line, glance, see it, repeat until you no longer see it with a glance. Then use the CYA value one step above the line you read. So if you stopped at 50, use 60 ppm CYA.

The vial is in logarithmic scale. So it is not viable to interpolate between the lines. Just use the whole numbers, such as 50, 40, 30, ....

Thank you, I think I am over staring at it, and I just realized that I did not round up the CYA reading to 40, it was still on 34. Now it is telling me to add a lot more bleach. Live and learn.

Does it appear that I should be adding even more chlorine? I am following the Pool Math, but not even getting close to the SLAM level. I feel like my local grocery stores are going to report me for buying so much chlorine. And the times on my log don't match actual times that testing and bleach additions have been done.
