FPM,
use the Proteam or order some Jack's magic. I think it is easier to prevent stains than treat them. DO NOT SHOCK THE POOL 24 HRS BEFORE OR AFTER USING METAL OUTS !!!. Some shocks have cal hypo in them and adding calicum and metal outs cause a big cloudy mess.
clean those cartridge filter with electrosol dishwasher detergent mixed with water and soak em overnight in a big garbage can. they should spray clean the next day. best thing i ever did was replace those cartridges with a sand filter and i talking a brand new pool with carts only 1 month old. what a PITA to clean those things.
also order Dave's kit. it's great and i use it myself.
