Everyone's been "pool-stored" at one time or another--but most of us have had someone on PF point it out to us, rather than pick it up on our own, as you did.

With a CYA of 100, to tell someone to reduce an FC level of 12 to 4 is like telling someone with pneumonia to go skiing! Just not right.

You CAN get refills for the CYA reagent -- Taylor Reagent # 0013, I believe. I keep a pint bottle in a dark, cool cabinet, as well as other refills. But, with care, you'll easily make the end of this season with your new K-2006.

That your water is clear is a really good sign. That means we will get you to adjust chemicals, but you don't have to FIGHT a problem, like algae.

Once we know the true T/A (and the K-2006 will tell you that) we can guide you to lowering it. We'll also know the true FC and CC levels. Your "Shot Glass" measure of 12ppm is for total chlorine (TC) and the "Shot Glass" measure isn't very precise (that's no reflection on you--I use the shot glass because it's very easy to dilute more precisely that way), although it works as an excellent "Plan B" method.

If, what Ben suspects and suggests is true, that your CYA is actually much, much higher than 100, then draining and refilling much of your water will be in order, and that may TOTALLY alter your T/A level as well. We'll cross that bridge when we come to it. Luckily, with a smaller pool, it's less painful to do so.

But please don't just empty the pool and refill it....bad things can happen from doing that, especially if you have a lot of ground water around the pool (it can float, like a boat--very, VERY bad!)
