Well, trying to keep a denitrifyer properly tuned, is not
exactly making things easier.

Live rock and a deep live sand bed in the tank will
denitrify the water.

But as for making a denitrifyer all you need is an area
for bacteria to grow in a container (usually tubing) where
the water flow is turned down low enough that the oxygen
is used up.

I'm sure that this subject pops up in waves, but as I'm new to online
forums/groups/blogs/whateveryouwanttocallit...

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...
