So I did throw in 2.5lbs of powder shock yesterday but removed all pucks from skimmers. Today I tested the pool and here are the results:

FC 0.5
CC 1.0
TC 1.5
pH 7.5
TA 120-130
CH 340
CYA 100

So what's my next step? I'm going to home depot now anyway so I'll be checking the thread periodically. Maybe I'll pick up some bleach?

I pick up bleach each time I go into town since I live in the country. Better to have too much than not enough I always say. But I am not the experts on here. I am a newbie and love this site.

You don't wanna hear this but............Your CYA is likely greater than 100. Do that test using half tap water and pool water and double your results. You should drain and replace water till the level gets into proper range for your SWG. Then you need to shock your pool using BLEACH! Also, noone here recommends use of the Nature 2 Thingy due to metals. Take a read through shocking your pool in pool school and see the CYA/Chlorine chart there.

I think Leo has the TF100 XL :goodjob:

Yeah, pick up plain unscented bleach or liquid chlorine. You are gonna need it.

As Woody said, that CYA needs work. I suggest you retest the CYA using the dilution method. Use 1/2 pool water and 1/2 tap water, then the reagent and test again. You should double the test results. This is not accurate, but it will tell us if CYA is closer to 100 or 200

You can pour the sample back and forth as often as you need to help confirm your reading.

I do have the XL version yes :)
My CYA testing was interesting because I kept adding the water and kept seein the dot, not very well but I did see it so I'm assuming it was 100. Even going further I could still see the outline of the dot but it was so murky I decided to say it was 100.

Wait it sounds like you filled the CYA tube and still saw the dot. Is that right? That would mean you have low CYA.

Just want to bee sure before you drain.

No I could still somewhat see a very murky dot when I was at 100ppm but started to doubt myself and just said it was 100ppm.

As a side note: the water is crystal clear and sparkling lol.

That really does sound like you may have made a testing error. A CYA reading of 100 will mean that you would have put about 1.25" of water in the tube and the dot disappeared completely.

There is a link in the CYA Extended Test Kit Directions (in my post above) that has pics of the test. It may help you get a better read on the test. Many of us have a better handle on the test after viewing the pics. :wink:

Very good news :goodjob:

you should not see the dot at all. you can keep pouring back into the bottle so you can experiment with the test. Really go until you cant see the dot at all.

If you are going to replace water realize you will be pumping out whatever chems you add.

I suggest that you do add some, maybe 10 PPM FC. Until you can confirm the CYA test, my opinion based on your description is that your CYA is maybe low, not high.

I didn't add any as I already left and my filter doesn't run overnight. Programmed to run all day though so I'll add it in the morning. I'll redo the all the tests in the morning and try to be accurate.

If you fill the CYA testing tube completely, does it look like Image A, B or C? The tube in the images is part of the chlorine test block but the tubes work in the same way.

I read and re-read the postings and it's not clear what you meant.
