Hi, ever since i removed a few plants i had, I'm getting green algea buildups on the glass and green cloudy nasty looking water. I have a 35 gallon with 5 (small to medium) african lake malawi cichlids. I have an 80 watt lighting system (Orbit by Current-USA) that i run for 7 hours a day (2pm - 9pm). I have a penguin 350 biowheel filter. the tank is no where near a window. I'm using freshwater sand as a substrate. I never had any algea problems until I removed the plants and upgraded the lights. I have been doing weekly or even biweekly h20 changes and have had no issues until i removed my plants and got the new lights. Since the cloudy h20 started, i have been doing 33% h20 changes every 3 days for the last 2 weeks and it gets little bit better but in a day or 2 looks horrible again. I'm thinking of getting new plants this weekend. Besides lowering the lighting times is there anything else that might help? My tank used to be crystal clear and it would last for like a week and a half and still look great. Now it's a different story.
