Algae Scrubber theory question
Some claim their ATS reduce or eliminate tank algae. It makes sense in unplanted tanks where excess nutrients are the cause but what about the claims I am seeing that algae is being reduce in planted tanks by giving a prefered optional growth site within the scrubber??? It does not add up for me. I would expect normal algae formation in the planted tank no matter how good the conditions are in the scrubber since the tank conditions remain at least somewhat favorable to algae growth here too. What do you think? Are these claims valid?
