January 13th, 2017. A better harvest this cycle. There was about 2/3 cup of algae with a dry weight of 1.60 ounces. Since this harvest landed on a Friday (which is my normal tank maintenance day), I'm going to let the scrubber go a week this next cycle. Even though it takes no more than 15 minutes to maintain the ATS, making it a part of the regular routine will be more efficient.
