I'll get some muriatic acid (not sure if the liquid is available) might have to use the "ph down"
I did check the swcg manual and the cya is supposed to be at 30 - 50 ppm with a max of 150

I definately need the stabilizer the chlorine levels are nice and high-normal in the morning but by the afternoon its on the low end of normal
I'm having a hard time locating a testing kit that does more than ph and chlorine levels I have hth 4 way strips but I don't know how accurate they are and I would really like a kit that would measure the cya levels, or else i'll have no idea how much is in there

I'm in canada and it seems the taylor kits are not available here, or are atrociously expensive
