gha- green hair algae gfo -Granular Ferric Oxyde Phosphate (removes phosphates from the water) Yes your old sand would be a major factor. Have u tested NO3? if you can remove it and rinse it or replace it it will help big time. the old sand probably had a big die off and had ammonia and nitrite the bacteria was working on. |
