Aquaponic system ph level and nutrients

[GpsFrontier]

Hello kr3t3n,
I don't really understand the question.

First, Aquaponics is simply just a method of making your own nutrients. Second, I don't understand what you mean by "clean". Are you meaning consume the nutrients? Third, what two watering methods are you referring to? Do you mean high and low aeroponics? Fourth, what do you mean by "ebb&flow or DWC to have more time?"
