Trying to get my pool clear. Using SLAM method to the best of my ability lol.

[Mdragger88]

Unless u pass ALL 3 end of slam criteria you aren’t done & the problem will return.
Crystal Clear water is only 1 of the criteria.
You did not list your cc’s.
Have u done an Overnight Chlorine Loss Test at adequate fc levels?

 

[Nicholasholmes424]

Following your advice and installed recommended chlorine from math calculator to SLAM to recommend 12ppm with a CYA of 30. I put it in at 10pm when the family got out of the pool. I'll test for when I get out the shower with my FAS-DPD test kit and add more chlorine if needed and will retest in the morning to see how much I lose overnight. How much loss is acceptable to be considered a finished SLAM and ready to just maintain? Also thank you for all your responses and helping me through this process. I truly appreciate it

 

[Mdragger88]

Read through the directions & follow exactly - you must test after your last dose to know exactly where you are starting from- a loss of 1ppm or less & cc’s of .5ppm or less is acceptable
Overnight Chlorine Loss Test
If u pass then you can maintain target fc levels for your cya at all times FC/CYA Levels
Allowing fc to fall below minimum for your cya will allow algae & nasties to grow.
It is safe to swim anywhere between min & slam fc level for your cya so long as u can see the bottom of the pool.
Many choose to maintain a little higher than target levels so they never broach minimum especially due to higher uv days or instances of high bather loads.

Get rid of that other app if it says your chlorine level at 2ppm is fine.

I am popping to say THANKS to @Mdragger88 for doing the heavy lifting on this thread. @Nicholasholmes424 your pool has come a LONG way! Well done!

I am going to give you three jobs for today:
1.Please fill out your signature. Create Your Signature - Further Reading
2. Jump in the pool with a toothbrush (SAY WHAT??) and clean all around everything-returns, skimmer face, ladder parts, ect. We just had one SLAM stall until the cleaned around the returns. Some *stuff* came off and they were able to pass the OCLT for the first time afterwards!
3.List your testing like this as it is easier for us to read:
FC
CC
PH
TA
CH
CYA

HAPPPY FATHER'S DAY
I have a lot of scaling on the side walls from previous owner neglect. It comes off but it's an extreme task to remove from a pool this large with a toothbrush or any brush lol. At 10:00 am EST test results
FC 12.6
CC .4
PH 7.5 (Between 7.4 and 7.6)
TA 120
CH 400
CYA 30 ISH (dot disappeared slightly above 30. 1/4 full at the top after it flares out)
Water Temp 90
Pool is very clear. Best ever seen so far.

 

[Mdragger88]

Did u test to confirm your fc level after your last dose of the night? Then test before sun shined on the pool in the am? If not then u can’t be sure of actual loss. U can try again tonight to be certain. If u pass in the morning then u just maintain target fc levels for your cya at all times to ensure it never drops below minimum & hopefully never have to slam again. That’s the goal after all! A trouble free pool !
That’s the great thing about testing your Own water & having a specific procedure like the Overnight Chlorine Loss Test along with the other slam exit criteria- you can have actual confirmation that there’s no organics remaining vs just depending upon how u think the water looks & hoping for the best.
After u are sure u have passed the oclt- you may want to increase cya to the 40’s to help combat daily fc loss from the summer sun be sure to up the fc chlorine target accordingly.
As far as the scaling goes - switch on csi tracking in PoolMath
Low ch is not an issue in vinyl pools without heaters but high ch is a problem in all pools.
Here’s more info on that

Calcium Saturation Index (CSI)

How is CSI calculated? Very simple – use our PoolMath tool. To ensure long plaster life and save money, click here to learn more.

Calcium Scaling

Calcium scale on your pool is something we all want to avoid. With some elbow grease and a pumice stone for pools we can help you remove this eyesore.

Not going to b helpful at all, but wanted to say that I like the pool, looks a lot nicer with clear water

 

[kimkats]

Well done on your "job"! THANKS

Yeah you sure don't want to brush much of the pool with a toothbrush. I am talking about using the toothbrush around the return eyeballs and other small areas.

I am glad to hear the pool is looking better than ever! Soon you will be able to put your pretty pool here: How Clear is TFP Clear?

[Nicholasholmes424]

CYA approximately 30 or slightly below. FC is 6.5 right now at 930PM EST it was 12.6 this morning at 10am EST. We have been in the pool for around 4 hrs. Should I do a overnight test from here?

 

[Newdude]

Should I do a overnight test from here

Yes but you still have more killing and/or filtering to go. I can tell by the fireball your light is throwing like a driving a car in the fog at night. The further the beam shines out, the more crud is in the water. You're getting close but still have some to go. Notice how this one shines every which way but towards the shallow end ?

Yours

 

[Nicholasholmes424]

Just tested and I have FC of 4.5 at 745am had 6.5 at 930pm. So this means I need to raise the chlorine back to slam level correct?/

 

[Newdude]

Yup. Full SLAM ahead. You should have raised the FC last night back to SLAM and used that as the OCLT values PM/AM. But that's OK. You didn't go backwards. You just kinda paused it for 10 hours.

I think he also needs to get his CYA in order as he keeps saying slightly under 30 or 30ish. That will give the UV an upper hand all day. Are you checking your CYA in sunlight as that's the best way.

Going to get CYA this morning the walmart was out and pool store was closed. Going to raise to 45 and maintain after SLAM. 95 degree days here and shade leaves my pool around 10 so full sun for 10 hrs

 

[Newdude]

Going to raise to 45 and maintain after SLAM.

You can't test between the 10s, as much as our brains want to. Add 10 ppm of CYA which should clearly get you to 30 or 40. Maintain 40% of the CYA as your target. (12 or 16)

 

[Nicholasholmes424]

FC16 at 9pm to 14 at 9 AM this morning. Raised my CYA to 40 did a lot of wall scrubbing yesterday due to bad calcium scaling.Fine green dust particles have settled that wasn't collected by polaris. Should I maintain 16 ppm all day or raise now to 16 and again at sunset. Going to vacuum on filter shortly. Water looks amazing but IK still not finished. Debris picked up from polaris is scaling deposits and scouring pad debris.

 

[Newdude]

M(aintain) the SLAM until the end. Be happy the FC mostly holds but keep your foot on the algae's throat. Then twist the foot.

Stay the course. You got this.

 

[Nicholasholmes424]

My PH has raised to over 8 but I'm slamming with
CYA 40
FC 16
PH 8+?
TA 130
CH 430
Should I try to lower it or leave it be?

 

[kimkats]

Leave the pH alone as it does not test rigth with the FC over 10.
