An improved algae scrubber system having a partially submerged rotatable drum (16) wrapped in plastic mesh or algae screen (18). The rotatable drum (16) is supported by a water treatment tank (24). The water treatment tank (24) is in fluid communication with a second tank (32) by way of an influent pipe (28) and an effluent pipe (10). The unique shape and placement of the effluent pipe (10) forces virtually all of the water to pass directly through the algae screen (18). This configuration also allows for an increase in stimulating turbulence for the algae while creating very intimate contact between the algae and waste laden water (34). The water flowing directly through the algae screen (18) discourages over population of herbivorous invertebrates by dislodging them.
