Hi all -
Must be pool season here in NJ! I did a test yesterday using my TF100 kit. My TC was 2.5. My pH is 7.2 and my standard free chlorine (the yellow part of the test tube) was between 8 and 10.
I did the CYA test and seems that there is none present in the pool? Reason I say this is because after doing the CYA test, I could fill the whole tube and still see the bottom black dot - it was crystal clear.
Last year based on the advice of this forum I switched from standard chlorine tables to the BBB method. Since the pool was just opened last week, the pool guy added 5 gallons of liquid shock and added the floater in.
I believe there should be a level of CYA present in the pool, but given that CYA turned out to be an issue last year (when I was still using the old chlorine method), I'm just looking for a gut check that I should add an stabilizer?
Now off to the green issue - it's metal stains. I know it's metal stains based on the vitamin C tablet method. Given that I have two issues, any advice on the best way to address both and in what order? I feel like I can tackle each one separately on it's own, but don't want to mix stuff up and negate anything!
If I need to provide anything further for background, please let me know. I'm out of practice from this horrid weather in NJ!

Also as a footnote, the sand in the filter was replaced just last year.
