Been in the hobby along time, never had this issue. My tanks have always been crystal clear and my fish very healthy. For some reason I'm having difficulty keeping the water clear in my 120g. There is a constant haze and green hue to the water, even after 50% water changes. Some additional information, I do water changes once a week, not a planted tank, light is on for about 10 hours per day, I feed Omega One Cichlid Flakes in the morning and Frozen Brine Shrimp or Blood worms in the evening. Any input would be greatly appreciated.
