Reaction to chapters 5 and 6

When reading through the chapters, these last two went more in depth on the external factors that can affect the system.

It was also interesting to read on how external factors affect the plants and bacteria more than the fish, when I would assume that it would be the orher way around. the more I read aBout these sYstems the more I understand the labor and care that must be put into them. While going over the different types of systems available, such as the barrel phonics, it seems as though one can build a system quite easily. Though what will ultimately predict your system's productivity will depend on how much you care for them.
