First time doing pool duties
HI it's my first time cleaning my parents pool and i've been reading this forum since i've started. I've been keeping the FC level high (I think but their test kit isn't too accurate) but it seems their CYA is 0? Yeah I know we really need to get one of those taylor kits. But it seems kinda hopeless because i've been keeping my eye on the fc for 6 straight days and the water is still green... any advice?

If the CYA is really zero, then the FC will drop by half every half-hour in direct noontime sun so are you sure 1) you have no CYA and 2) that you've got measurable FC in the pool at all times? If the CYA is truly zero, then the easiest way to increase it while also adding chlorine is to use Dichlor since for every 10 ppm Free Chlorine (FC) it also increases Cyanuric Acid (CYA) by 9 ppm.
