Yeah.

1. Filter 24/7.
2. Add a quart of polyquat, if available. It will help with algae AND removing iron and dead algae.
3. Add frequent 1 ppm doses of chlorine to the skimmer. Cal hypo would be best, but bleach will help too. 1/4 gallon of bleach or 1/3 lb of cal hypo.
4. In between chlorine doses, add 1/2 box doses of borax, added slowly to the skimmer. Continue these regularly, till you reach 7.0.
