Hi Tina;

+ Each gallon of PLAIN 6% household bleach will add about 2.5 ppm of chlorine to your pool: if your water is already "green-tinged", add 1 gallons to start.
+ Check and see if the Walmarts in your area have the HTH 6-way kit -- it is an EXCELLENT value, and compatible with the K-2006, which you'll need, but which will take a week or two to get.
+ Walmart will also have the bleach, and some 20 Mule Team borax -- both in the detergent section. I'd recommend getting 16 gallons of bleach and 6 boxes of borax. Add the borax 2 boxes at time, slowly to your skimmer with the pump running. Wait 4 hours, retest the pH, and repeat until the pH is above 7.2
+ Do NOT add baking soda; it will increase the chance of staining with the copper.
+ Remove the Floatron - unless you don't care about stains or green hair.
+ Do the white bucket test for copper: put 4 gallons of pool water in a CLEAN white plastic bucket. Add 1/2 cup of bleach, and 1/2 cup of baking soda. Mix, and cover. Wait 24 hours, and see if there's any staining or blue sediment on the bottom. If so, you have copper. If not, go ahead and add bleach 2 gallons at time.
+ Run your pump 24/7.

We call test strips, "guess strips" -- they can tell the difference between some chlorine and no chlorine, but that's about all.
