New saltwater pool start up

[Tattooed Nurse]

So here are my recent results from yesterday evening. Working to decrease pH slowly to get the TA down. I have been running my SWG at 50%. Is that why my FC continues to rise or is it because my CYA is so high? If it is due to me running the SWG at 50%, should I turn it off for a few days or just back it down to 25% and see where the FC is in a few days?

CYA amount won't cause Cl to increase, it just determines what the optimum level of Cl should be. Yes, just dial down your SWG to 25% and see where it ends up after a few days. Depending on sun, pool use, etc. you will then have to tweak it again up or down to find where it doesn't change much. That setting is not a forever setting - it will have to be occasionally changed as the seasons and pool use change. During the peak of summer, I had to be near 60%, then down to 40% toward labor day, and now only need to be at 20% with the less sun and cooler temps. You'll likely get into a routine of a weekly test, with perhaps an bit of a bump up or down every week or two or three.

Thank for the information!

I would turn it down, but for your CYA, you FC is no "too high." Always follow this...Link-->FC/CYA Levels

You should keep your FC at 11-13 for CYA of 100. The downside is that the pH test will not be valid with FC > 10.

You might let FC drift down to 10, check pH, then raise FC back to target range.

Very good to know! I always learn something new from you all! Thank you! I am saving this for future reference.

This is my most recent results from 2 days ago. I turned the cell off for a few days and then started it back up at 25%.

I have been testing my pH for 3 weeks now and I CAN NOT get it below 8! I have added 3 gallons of muriatic acid over the course of 3 weeks and it isn't lowering it at all. Any clue what I am missing here? TA has only come down to 190 at the lowest. We do leave our pump running 24/7 so not sure if that could be causing it to ariate and keeping the pH elevated.

 

[ajw22]

Do you test your pH 30 minutes AFTER adding the acid.

Your TA of 190 is causing your pH to bounce back rapidly after you add the acid.

What is the pH and TA of your fill water?

If you can get tour TA down to around 70 your pH will rise slower.

Lower Total Alkalinity

A lower Total Alkalinity level can help a pool owner stabalize their pH increase. We'll explain how to lower TA with a little help from muriatic acid.

Just checked my fill water and the pH is 7.4. I am still running a pH of 8 no matter how much muriatic acid I add. I would have responded sooner but we have been on vacation for a week. Thanks for your help!

Another thing to consider is that your logs often show FC over 10 which causes the Ph to test falsely high.

Let it drop below 10 and then see what your Ph test looks like.

Will do! I turned my salt cell off last night because the FC is a little to high for my liking at 11. I really appreciate your suggestions

What is your CYA?

With CYA of 100, you need to keep your FC up. Follow this link-->FC/CYA Levels

Its ok to let the FC come down below 10 to check pH, but you need to keep adequate FC for your CYA...

My CYA is at 100. Maybe a little higher actually but the Taylor only goes to 100. Thanks for the link!

We need accurate CYA to maintain proper FC.

Do the diluted CYA test, starting at #8 here:

CYA - Cyanuric Acid Test

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

Yes sir! I will do that right now

 

[Tattooed Nurse]

Yes sir! I will do that.

CYA is at 95.

 

[proavia]

CYA is at 95.

How did you measure a CYA of 95?

Did you do the diluted CYA test?

If the CYA falls between the lines on the test vial, round up to the larger numbered line.
If the reading falls between 50 and 60, round up to 60.
If CYA is greater than 90, do the diluted CYA test.

 

[PoolStored]

CYA is at 95.

^^^Is that your doubled number? When you diluted, what CYA did you read on the tube?

It was between the 90 and 100 when the black dot completely disappeared

It was between the 90 and 100 when the black dot disappeared. I'm not sure how to do the diluted test. I'm very new to owning a pool. So it would be 100. Got it!
