1. Go to Walmart, etc and purchase 16 gallons of PLAIN 8.25% household bleach and a cheap OTO (yellow / red drops) test kit. You can use it to clean up your pool as is OR to get by till you get to the next steps.

2. If you start refilling, add 1 gallon of bleach EACH evening, till full.

3. You'll need to get some stabilizer quickly. If you have a Sams Club nearby, purchase one of their 24lb boxes of bagged Pool Brand shock. This product line is one of the few locally available brand of undiluted dichlor. Your pool has a PF of 7; undiluted dichlor is about 55% available chlorine and 50% stabilizer (not a typo -- lo-o-ng explanation, tho), so: 7 x 24 x 0.55 = 92 ppm chlorine and 84 ppm of stabilizer. Using 1/2 of that box will put your stabilizer around 40 ppm, very cheaply and easily. The rest of the shock will keep till next year.

4. Order a Taylor K2006 from Amazon. These are NOT available locally; there are links and explanations on the test kit page linked in my blue signature box. Also, read the Best Guess page linked from there.

5. Do not worry about phosphates.
