50,000 gallons and TA is 230 this am

[HELICOP]

What a fantastic site. Too bad in took me 2 years and lots of $$$ before I found it. I went to the DIY store and built the aerator inspired from Rangeball back in the day ( you can find it here on TFP - search for "my aerator"). I also pick up a couple go gallons of muriatic acid. It took 2 hours to build the aerator because I am slow. No glue necessary, all fittings held through PVC pipe pressure and it is actually is working. I will post a pic in about 5 mins. Total cost = $30.

Here are my numbers as of this morning:

pH 7.2
CH less than 1 --- just converted this year to a SWG that is not keeping with my demand yet. I have shocked twice in the last 48 hours and adding CH tablets in skimmer to help until the SWG kicks in.
TA 230
CYA 100

So, the plan is to aerate the water until TA comes back with acceptable limits and use the acid to lower pH as needed. Am I on the right path other than needing a lot more Chlorine?

Welcome to TFP!!

Have you discovered Pool School yet? Start with these:
ABCs of Water Chemistry
Recommended Pool Chemicals
Water Balance for SWGs

Note that CH here means Calcium Hardness. What are you testing your pool with?

You CYA appears to be too high and if the SWG can not keep up, it must be due to something in the pool. To fix that, you might need to replace some water and then follow the ShockLevelAndMAINTAIN Process.

Forget about the TA right now and focus on getting the water back under control and safe. TA is about the last thing to worry about.

Thank you for the quick reply. I'm using a Taylor K - 2005. I will focus on shock, level and maintain process.

Your test kit is devoid of the most important test we need: The FAS-DPD test which tests FC up to 50ppm.

You can order it individually and it will make your kit equivalent to the K-2006 kit we trust.

TFTestkits.net is the site to order it from TFTestkits.net

Roger. Ordering now. Thank you.

Perfect on getting the FAS-DPD test! Redo your CYA test with the dilution method. Here are the instructions: Pool School - CYA

I have the K-2005 it will work. However the titration method, which is what you just ordered, is superior in every way. When my reagents run out I will order the ones for the fas-dpd. However, either will work it is just a matter of ease and accuracy. I got mine for such a good deal I couldn't pass it up.

GL with the slam I am still in process on my swamp and am 2 weeks strong. Post some pics when/if you can.

Thanks

The OTO will not give you an accurate result above 5ppm. It's just a guess after that. The FAS-DPD goes up to 50 ppm.

 

[rahimlee54]

K-2005 has the DPD test not the OTO based on everything I can find on the net. Please correct me if I am wrong.

[MarianParoo]

You are right. The DPD in the 2005 goes to 10ppm.

 

[jblizzle]

You are right. The DPD in the 2005 goes to 10ppm.

If you can differentiate the shades of pink. As stated above the FAS-DPD is far superior.

 

[MarianParoo]

Amen. Wouldn't want to test without my FAS-DPD!!!

Helicop: let us know the results of your CYA dilution test.

 

[rahimlee54]

I think it'll do 40 ppm with correction factors, I will be glad when I trade up though ?.

I will post the results the day my kit arrives. It has already been shipped. Thank you all.

 

[MarianParoo]

Great! You can do the dilution test with the 2005, btw. No need to wait to know where your CYA is.

 

[HELICOP]

Ok everyone. New kit arrived today. Here are my numbers.

FC - .5
CC - 1
PH - 7.6
TA - 190
CH - 550
CYA - 100

Let me guess, drain the pool to get CYA within acceptable range 80 or less and then incorporate SLAM. Sound about right?

 

[jblizzle]

Sounds like you got it

Might try the CYA dilution test to see how far above 100ppm it might be.

 

[MarianParoo]

Do the CYA dilution test linked below to determine how high your CYA really is. Let's go from there.
