I was analyzing how the scrubber works and also noted that algae travels across the surface of the water not so much through it. So when I had the chaeto algae break the surface of the water it turned purplish brown with algae. Using a 18 gallon tub for a 120 gallon tank.
Using a small 18" fluorescent light that is on 24/7. I don't notice any swings in my PH. Stays constant between 8.13-8.18.
