I'm working on CYA right now. I added half the recommended dosage and I'm waiting for it to dissolve. Once I put the other half in it should bring CYA upto 30 ppm. I do have an Intex and their recommendations are 30-50 ppm. I had read somewhere on here to keep CYA at 80-100ppm for SWG, I wasn't planning to go that high just yet but would that be wise if Intex says 30-50?

I do have a taylor test kit and I will test levels tomorrow.

I am going to add cal-hypo 65%. I am also going to add a metal chelator. Can I add both of these things at the same time, I want to do it tonight around 9:30, when I get home from work or should I wait on the cal-hypo? I will not add salt until CYA is at least 30ppm and TA rises (currently at 70) and PH rises (currently at 7.2) I'm assuming the CYA will help both rise slightly?

Do you think the chelating agent will introduce phosphates into the water?
