Update: OCLT Results and Next Steps. Question Re: OCLT

[Texas Splash]

Does that seem like a a lot?

One gallon is about 10 ppm of FC in your pool. Early in the SLAM you could easily use 2-3 gallons per day. After about a week hopefully just topping it off once or twice a day. You're in the ballpark, but somethings is still eating chlorine. You just haven't exposed it yet.

As for the drain covers, they are usually held in place by some screws. The most difficult part is holding your breath long enough to unscrew each one. We'll watch for your OCLT results in teh morning.

Thank you so very much. I appreciate the validation. I will post OCLT results in the am.

Thank you so very much. I appreciate the validation. I will post OCLT results in the am.

Results:
PM: FC 16.5 ppm and CC 0.5. (Guess I over poured LC last night)
AM: FC 15 ppm and CC 0.5
1.5 ppm loss
Clear water
CYA - 20

Should I add stabilizer?

Should I add stabilizer?

Yes. 20 is just too low. You need at least 30, even 40 isn't a problem. So close on that OCLT!

Ok! Will raise stabilizer. Can I continue to SLAM while I have the sock of stabilizer in the pool? YES, getting closer. Phew.

Absolutely!

 

[ald2002]

Absolutely!

Going to add now. Good to know I can add chlorine while raising my CYA at the same time.

 

[ald2002]

My very first stabilizer treatment. Used enough to raise 10ppm. Can reassess if more is needed later. Can I add LC to the same return? Sorry so new to this but promise to pay it forward!

 

[Texas Splash]

Can I add LC to the same return?

Sure, no problem. Cyanuric acid is not as potent as muriatic acid. After that sock has soaked for about 30 minutes, feel free to squeeze it continuously. It should all come out of there like mush after a few minutes of squeezing.

Thanks. When do you suggest I test CYA again?

Give it a couple days and just assume (for now) it increased by 10 ppm.

Perfecto! Thank you so much.

I passed the OCLT!

1. Overnight loss was 0.5 ppm
2. CC Is 0.0
3. Water is clear

What next?
1. Do I monitor for another day and perform another OCLT tonight?
2. When do I start my SWG?
3. How soon should I test TA, pH, CH and salt?

@Texas Splash you virtually held my hand through every step and I appreciate you and TFP so much!

 

[Texas Splash]

What next?

Well first ......

Other than that, the FC will fall on its own. Just keep an eye on it and maintain it in the normal target range note on the FC/CYA Levels. Once the FC falls below 10, you can test and adjust your other levels and enjoy the pool. Good work!

Thanks! Wait until I drop to 10 and start up the SWG?

Yes, that's fine as well. Now is also a good time to ensure the CYA is at about 70 for optimal SWG efficiency.

Thanks. Here’s my plan please weigh in. Also please let me know if # 2 should go before #1.

1. Fire up SWG - maybe start at 30%?
2. Increase CYA - just added yesterday to bring up to 30. Will add slowly and add enough to bring to 40 today. Test in a few days and add more. Question - since my CYA is below level for SWG and until I get it to minimum, what FC level should I aim for?
3. When FC is at 10 perform full spectrum testing

Question - since my CYA is below level for SWG and until I get it to minimum, what FC level should I aim for?

Unless your pool gets a lot of shade, I would increase the CYA to at least 60 for now. The FC holds much better in the pool when the CYA is in that 60-80 range. Starting the SWG at 30% should be a good place to start.

 

[ald2002]

My pool is starting to balance again. How long does it normally take for FC to reduce? I am at 10 ppm. Guess I will give it time. My TA is a bit high @110. Is it normal for TA to spike?

Also since I have iron I bought Jack Magic (salt) cannot recall the color. When will it be safe to add?

Thanks again for EVERYTHING!!!
