Have my 2006 test kit

[Raceman]

But I suspect I am doing something very very wrong!

So did my first set of tests and got the following results;

fc - 37
ph - 7.4
ta - 120
ca - 400
and CYA so high I can't measure it!

Are some some beginers errors I may have made that I need to correct?

As I was passing Leslies on the way to work, I took a sample in there, and they measured

fc - 37
cya - 80

cya unchanged since last time, and fc higher as the greeness has now gone, and we have been using 8.25% clorox from walmart (marked concentrated) to deal with the greeness etc that I have posted before.

Any suggestions anyone before I start pumping all my pool water away lol.

Welcome to TFP

Your CYA testing is likely much more accurate than the pool store once you get the hang of it. Have you tried diluting your pool water with tap water by 50% to do the CYA test? How is it that it is so high you can't measure it?

Your numbers look plausible, and we have had so many problems with pool store results (especially CYA) that I never trust pool stores any more.

Hi,
Thanks for your replies.

Hi Aimee,
The house hasn;t been lived in for about a year, but water was nice n blue when I 1st looked at it, so suspect a pool service has been attacking the pool upto now.

Jason, I will try that later on/tomorrow, just for my interest, I got it tested at the same place I did last week, and they read it CYA at 80, mind you, another Leslie's made it 50 a couple of days before lol

Make sure the CYA test is done outside with your back to the sun and the tube at waist level. Pour back and forth a few times and see if you are consistent.

I tired it back to the sun, in the shade, will try again tomorrow.
