5gal dwc mader

[Maat Aatack]

It's quite the beast this thing is, and I'm impressed with the hydroponic thing. So the setup is natural light in a 5gal with a bubbler stone. Gets lots of light and goes through 10 gallons in a few days (one feed and one top off). I don't have a ppm meter, so I'm doing a complete water change every 3 days. am i doing it right?
