Russ,

The EASIEST way to rid your tank of excess nitrates is with a refugium
and some macro algae. I highly suggest chaeto. Since I added chaeto
to my sump my nitrates have consistently been at 0 for over 6 months.

Has anyone had luck with external denitrification filters that don't
need to be fed? If so... Can we talk about the design?... Thanks...

FYI I'm looking to start a custom 32 gallon reef in a friends house
and was just playing with a few ideas on ways to make her life easier...
