I’m totally new to TFP and it’s my 3rd summer as a pool owner, acquired the pool when I purchased the home. Our pool has been cloudy blue for about 3 weeks now and am getting fed up with taking water samples into pool store and their recommendations. I’ve attached a picture of what our pool currently looks like. Please help, not sure what to do from here. Thanks!

Welcome to TFP and great job on getting your kit. BTW, it is your CC that equals zero. TC, or Total Chlorine is the sum of FC and CC, and the k-2006 doesn't measure that.

So correcting the problem will require following the SLAM Process. However, your CYA is rather high and it would be worth considering replacing some water first to bring that down. If you are able to drain and replace half of your water that will bring your CYA down to 40 (give or take due to the imprecise nature of that test, make sure to test again afterwards to confirm) which will let you SLAM at lower FC levels (meaning less chlorine) and make things a little easier going forward. You can SLAM and maintain the pool with your current CYA if replacing water is a problem, but it would be much easier to bring that down.

Just a word of warning: if you are using chlorine tablets to chlorinate, that is what raised the CYA level up to where it is. We always encourage people to manually chlorinate with liquid chlorine and save pucks for occasions like vacation. Anyway, just throwing that out there, best of luck with the SLAM!

So I’ve tried draining water and adding new and my CYA is still the same. So after the calculations is saying Slam FC 31....what does the mean? I don’t understand how much liquid chlorine to add.

How much water did you drain and refill. You needed to do at least half the pool volume.

Just below the jet. I can’t drain it more than that. Or at least don’t know how.

How much was that? 6", 12"?

You need to use a sump pump or get a siphon going.
