Ahhhh...just one more reason to like the 80s and 90s more!! LolRunning water horizontally over a screen at the surface will grow turf algae. I believe this is how early scrubber designs were back in the…80s? 90’s? I forget when, it was before my time in the hobby
Edit:the “horizontal river” style scrubbers were from the 1990’s into approx 2007
Do you think I would benefit any if I added an air pump to my contraption by maybe placing tubing beneath the screen?
