Don't spend money on anything but chlorine and acid to start. Keep pH very
low and superchlorinate. Chlorine alone will fix just about anything if
you keep the pH low. Chlorinator solution raises pH, so you'll need lots
of acid to compensate; this error is what confuses a lot of people. Algae
loves high pH, and high pH disables chlorine.

Once your water cleans up, you can balance it for the comfort of human
beings.
