Thanks Carl. I vacuumed today & got about 80% of the bottom surface, added about 5 gal of bleach & will brush tomorrow and start up the Polaris.
Questions:
1. Should I be using bleach to shock (meaning to bring the Cl level up quickly) ?
2. For how long should I look to hold the shock level?
3. Then how long should I wait before beginning to add CYA (wait until the water is clear?)
4. I do not have the trichlor tabs, what might I use to add CYA? (or if I need the trichlor where should I get them?)

*Current status - After about 5 hrs my green slim walls have started to clear, CL was up to 2. (thanks for the helpful NJ neighbor info!)
