Hi There, I recently built an algae scrubber in order to remove nitrate from my system. My scrubber is not growing lots of algae, there is a bit of growth but nothing close to an amount that I could harvest. Any ideas? Here are the specs:
The mesh is 4ft by 15in (1.2m x 38cm) it's 3 layers of plastic canvas.
Water is supplied to it by a 3/4 HP pump, which runs at 80-100gpm, the water runs over it fairly evenly
6 grow-lux bulbs (3 on each side) 40w each, they are on a timer from 7am to 5pm, no part of the mesh is further than 3-4in from a bulb.
I've tried reducing the flow significantly and that only helped a bit.
The screen has been ruffed up significantly with the whole saw method.
Thanks, Chester
