Hi Anji;

1. If you can, verify that you have a full level of sand in your filter. You can do the DE test to see (1 quart DE powder in the skimmer => if it shoots back into the pool, your filter needs repair -- probably more sand.)
2. Start adding 3 gallons of plain 6% bleach every evening. Get a cheap OTO (yellow drops) kit. Add 3 more gallons the following evening, if the chlorine level is below 5 ppm. Repeat, and so on.
3. Once the water has turned cloudy blue or gray, add 3 more gallons, and brush the bottom. If it turns green (from algae sludge) add 3 MORE gallons.
4. Filter 24/7
5. Use the cheap kit to check pH. If it's below 7.0, add borax -- 1 box at a time, added SLOWLY to the skimmer with the pump running -- wait 4 hours and retest. Continue till the pH is 7.4 or so.
6. If the pH is above 8.0, read the muriatic acid page, buy a gallon of acid, and add it 1/2 gallon at at a time into the pool, near a return. Wait 4 hours, retest, and repeat as needed till the pH is 7.6 or so.
7. Once you get the K2006, tell us what the test results are, and what your pool looks like.
