Test kit arrived today so here are my results. Thanks in advance for input.
I know the chlorine is low I added some bleach early in the week to get by.
Pump has been running 9 hours/day with the SWCG at 100% output.
Water has been clear. No rain since the outbreak though.

Chlorine
FC .8 ppm
CC: .2 ppm
pH
just above 7.8 and took 1 drop to lower it to 7.6
Alkalinity
80 ppm
CYA
unmeasurable - the little black dot never disappeared even when the tube was full!
Calcium (i ran it just for testing practice)
140 ppm

I remeasured my pool today and it came to 28,000 gallons.
17' wide X 40' long X (8+3/2) X 7.5 = 28050
For calculations should I use that number or round up to 30k or down to 25k?
I measured square but my corners are 45 degree angles but the stair area kicks out so the shallow end is wider.

Our Lowe's had no cyanuric acid stabilizer type product.
I called home depot like 30 miles away and they have it.

chemicals I have on hand
a 4 lb box of baking soda
around half of a 14 lb bucket of old cyanuric acid that was left from old home owner (closed in garage kept)
a gallon of muriatic acid
a bucket of 3" chlorine tablets (regal brand i think)
some "super blue" stuff that says it polishes the water (should I trash this stuff or use it one day)
a partial container of ProTeam Severest Algae Treatment (7% copper main ingredient)
