We Have Nutrients
Seeing algae in your aquaponics system is a double-edged sword. All that green tells you your system is cycled (or cycling) and that you have nutrients galore. On the other hand, all that algae has a life cycle of about 24 hours and the deceased algae create a lot of ammonia, which is not good for your fish. We have no fish in the system, yet, so I scraped out the worst of it and we will hope for the best.
