Im at a loss.......?

[tommyboyrn]

So I have been doing SLAM on my new pool due to algae growth because i didnt get enough chlorine in it while they were doing dirt and concrete work......

So yesterday it was clear and yesterday evening it rained and alot of dirt git back into it. Ive vacuumed it yesterday and this afternoon when i got off work...added chlorine last night and now water dingy..not muddy but not clear. I can see main drains in bottom and test results this evening as follows from a TF-100 kit

FC-32
CC-0
TA-140
Salt level about 3400

Filter running 24/7. Ive vacuumed to waste to get dirt out this evening before testing.
I am planning on checking before sunrise to see if my chlorine drops but is there anything else I can do to get crystal clear water? I have company coming this weekend....

What is your CYA?
How long have you been following the SLAM process?

 

[ctrav]

Hang in there Tom! These folks will get you back on track...

 

[tommyboyrn]

SLAM levels started Saturday....CYA yesterday was close to 80 but when I vacuumed to waste I refilled and the CYA tonight was close to 50.

Thanks for helping me I appreciate your time

 

[jblizzle]

Unless you vacuumed out over 1/3 of your pool, the CYA could not have dropped from 80 to 50.

Have you tried the Overnight Chlorine Loss Test?

Might just need a lot of filter time to pull the dirt out.

 

[tommyboyrn]

Im doing it tonight......just checked my chlorine and plenty there.....around 34 ( my kids dumped extra half gallon before i could stop them)....gonna recheck early AM with full test again

[tommyboyrn]

So this morning my FC dropped after i checked again late last night after kids dropped in more bleach it went up close to 42 so i get up this morning.....and
Pool clear YEAH.....FC levels dropped to 35 now CYA 70 (must have been error somewhere on the 50 reading)
So I will continue to monitor today and recheck tonight.....

So if its clear water and FC stays consistent then im done with slam correct

​From the SLAM page

You are done when:

• CC is 0.5 or lower;
• You pass an OCLT (ie overnight FC loss test shows a loss of 1.0 ppm or less);
• And the water is clear.

How is the filter pressure? Time to clean it?

 

[tommyboyrn]

Yeah i backwashed last night and got bunch dirt out

 

[tommyboyrn]

Okay so pool clear today.....chlorine dropped this morning and had to add some this afternoon when i was at work.....i come home and begin testing
FC 37
CC 2
CYA is 50....idk why the loss..i checked it 4 times from different locations in pool
pH 7.8 via color indicator
....uggggghhhh this is frustrating......

Tom it will come around! Take the small victories and keep fighting...

CYA is one of the hardest things to read and adjust so lots of patience needed.

 

[tommyboyrn]

Thanks ctrav.....i have added CYA little bit less than what poolmath advises just so i can tweek it better and slowly get levels up.

Tom

 

[ctrav]

Thats a very good way to do it...

 

[zea3]

Tom, don't add CYA during the slam. If you get a consistent result that is lower just adjust the slam FC target level accordingly. Retest CYA and adjust as needed after the slam is over.

 

[tommyboyrn]

Okay.....will take out cya and let it ride out.....will recheck chlorine in morning

 

[1RtBstrd]

Have you used the CYA standard that came with your TF-100 to verify your test methodology? I was having very inconsistent readings on my CYA level, then used the standard to hone my method. Try different lighting, vial positioning, etc... I found that I had to shake the R-0013 bottle before adding to the sample in order to get the desired reading when using the standard. Now I shake all my reagents before adding to the sample when testing my water.

 

[tommyboyrn]

So this morning my FC 32 down from last night and my CC were 0.5.....

With that much drop i need to continue slam correct

 

[mikefamig]

I would continue the slam until I reached CC=0.0 and then do the OCLT.

On the other hand with the weekend here you could let the chlorine level drop to safe level for your CYA and swim in it. Then just continue the SLAM on Monday.

Mike.

 

[tommyboyrn]

Pool crystal clear...had wife just check FC 30 with no cc.....
CYA 50

So with that I would continue to monitor and tonight recheck and test the OCLT since CYA 50 correct
