Hi Keith;

1. Take some pictures and send them to poolforum@gmail.com (pictures or links to pictures); bigger is better than smaller.
2. Test your pump, by filling it the pot with water, leaving the lid off, and briefly turning it on. It should empty the pot, but the water may run back. (Wear a swimsuit or something -- with some pumps, you'll get wet doing this.
3. If the motor rotates, but the water isn't pumped out, it's time to check the impeller.

Let me know what you find, and I'll take a look at the photos when you send them.

Meanwhile, use plain 6% household bleach to keep your pool from turning green. On Google Maps, it looks about 30' long, so I'm guessing 15 - 25K gallons? Add 3 gallons per evening. Get a cheap OTO test kit or better, a HTH 6-way kit from Walmart. This store:
Walmart store #1747—Perris
2560 N Perris Blvd
Perris, CA 92571
(951) 940-0440
has them in stock. You can also get PLAIN bleach there.

Test the CYA level with the HTH 6-way, and let us know. You may need lower or higher chlorine levels, based on the CYA. (See the Best Guess page in my sign, for the Cl/CYA relationship, and the test kit page, for more info there.)

Skip the bleach dose in the evening, if you have an OTO dark yellow or orange reading. Check again the following evening.

Good luck!
