If you want to get into how the natural freshwater and saltwater bodies operate on a biological level, these college biology videos will show you. Since our Santa Monica Filtration algae scrubbers absorb nutrients naturally, and also grow food naturally for fish, it's nice to see how the biology works.

The videos from this biology professor are from 2008 when videos were limited to less than 10 minutes each, and have been slightly re-ordered here to make more sense if you have no previous knowledge:
