Instead of spending alot of money on such a unit, you could try an
alternative.
A natural alternative can be used: Mangroves. Mangroves naturally remove
organics from the water. You can read about this in the Eastern PA Reef
Club January newsletter http://www.netpets.org/~whorst
I have seen data where after 1 week of using Mangroves, the Nitrates dropped
from 100 ppm to .5 ppm.
