1. Use the 10ml sample -- it's accurate to 0.5 ppm, and that's plenty close enough. The smaller sample size saves test reagents.
2. Add 2 gallons of plain 8% bleach, this evening if possible.
3. Watch the Taylor test videos:http://pool9.net/tk-guide/4. Either before adding bleach, or else sometime tomorrow, do a full set of tests on the pool EXCEPT the CYA test. I assume you've added no CYA, so there's no need to test for it yet. Post the results here.

5. Unless there are metals (iron!) in your fill water, you CAN use the SSR approach, but you'll have to scale the doses up your pool's size, which is 17.8 gallons, assuming a 54" side wall. However, you can only use that approach for the first two months.
Good luck!
