Yes, that is one heck of a thread, not the least because of the extraordinary photographs that accompanied so many posts. For our purposes, the discussion of bio load really begins in earnest at page 7 with the May 16, 2019 reveal that Mysiak has noticed some of his fish gasping at the surface in the morning, presumably after the CO2 level spikes during the overnight non-photosynthesis period. At that point, his 55 gallon NPT tank was stocked at nearly 400% per the usual "Rule(s)"!Yes! Thank you! I looked and couldn’t pin it down. I wanted to review it again anyway.
The above linked thread is a great discussion on this topic.
