Hey I have had my freshwater scrubber going for almost 2 months now and there is no growth. I have taken algae from my mini scrubber from my 10 gallon tank that i used to test to see if it would really work on freshwater and threaded it through the holes in the screen. My screen is about 7" wide and the lights I have are two 23w cfl bulbs about 4" away from the screen. I can't figure out why algae is not growing. The stuff I thread through the holes turns yellow and dies. I recently turned down the time the lights were on to 15 hours like my 10 gallon has but still no improvement. someone please help! I have attached photos of my scrubber.
Thanks
Drew
