Hi
I have a horizontal style scrubber.Its seems to run Ok but it seems to run far off its potential. Its roughly 4 inches wide and 9 inches long. I have around 300 lph going over it.
Light is a 10W red LED flood light roughly 3 inches above the scrubbr
I get green algae and come cyno(red algae) growing on it but it never seems to get thick or really take off as you see with most peoples. Any ideas?
I have cleaned it a couple of times (been going around 3 weeks with new light) and it does grow back but only very thinly
Any help on improvements would be great.
