Finally got TF Test Kit!

[cdereu]

I just got my TF Test Kit today and did my first testing tonight.

FC - .5
CC - 1
PH - 7.5
TA - 280
CH - 250
CYA - 40

Since my CC was 1 and my FC was just .5 I started shocking. I added 186 oz. of bleach and 22 oz. of stabilizer to get my CYA up. I need to check my FC & CC in another hour and if FC is down I need to add more bleach to keep it at 16 for shock level. Is this correct?

 

[Richard320]

Yes. Keep the FC level up.

It's too bad you already added the CYA, because as the CYA level rises, so does shock level. If it's tied in a sock, pull it out and put it in a plastic bag until the shock process is done, then hang the sock again.

You have it correct. If you want, do a OCLT tonight to see where you are.

 

[cdereu]

I never even gave it a thought about waiting to raise the CYA! I knew it was low and was worried about getting it where it should be. MY TA is also high, but my PH has been holding steady at 7.5. Should I try to get the TA down yet?

 

[cdereu]

just did a retest - FC is 17 and CC is still 1. Will check again first thing in the morning. Should I be taking my solar cover off while doing this?

 

[jblizzle]

I don't think the cover matters for the OCLT, but during the day the sun would help break down the cc.

New set of numbers this morning:

FC - 6
CC - .5
PH - 7.5
CYA - 90

Does everything look good? I think the CYA might be a little high.

I think the CYA might be a little high.

It is. You need to drain/refill about 50% of your water to get the CYA down around 45-50 so you can manage your pool much easier.

At 11:15 last night:

just did a retest - FC is 17

Then at 9:10 this morning:

New set of numbers this morning:

FC - 6

A loss of 11ppm over night?

That's a GINORMOUS hit, and I find it nearly impossible that you lost that much FC and CC remained below 1 (To be honest...with that much loss, I'd find it difficult to believe CC was below 10). Is the 6 above a typo for 16 perhaps?

 

[cdereu]

I thought 80 was the max CYA for a swg? Do I really need to drain 50%? I will retest my FC - I could have very easily figured wrong!

Looking at your cya numbers, going from 40 to 90 ppm is very unlikely unless you used a lot of liquid stabilizer. Are you having problems with the test?

You need to know this number in order to properly shock.

If you put only pool water (no R-0013) is the dot visible when the tube is full?

 

[jblizzle]

did you use liquid or solid CYA? Review the extended test directions to verify you are doing the test correctly .... It is a sticky in the testing forum.

You should not need to drain that much since you have a SWG. But it will require much higher FC levels for the required shock process.

I carelessly overlooked your SWG. I would get CYA to 60-80 but draining to 40-50 is certainly not necessary.
