Just discovered this board! I've got a 3 year old pool, and learned a ton from the old pool forum.
My question concerns testing for CYA. The 3 local pool stores near me give wildly different results, and only occasionally correspond to my calculated number. I want my own CYA test kit. The only ones I can find are part of a larger kit that usually costs $50 or $60. I already have a kit to test chlorine, Ph and alk, and that is all I really need. Is there anywhere I can buy just the vial with the black dot on the bottom, and then I can reorder the Taylor reagent or get that at the pool store. I just want the vial for the CYA test, or I've also seen the type where you can "raise" the black dot using a handle and stop when you see it. I would even be willing to buy a used vial.
Does anyone know where just the CYA test vials are sold?
