Anyone ever used a sulfur based de-nitrification filter, or have an opinion on its potential benefits\hazards?. Its reasonably recent technology and definitely appears to be more practical than the old style denitrification filters that required very specific amounts of a carbon doner to function properly.
PS: I realize the whole issue is a bit moot in an aquaponics system which is why I posted it in the aquaculture section.
Hi Arachdog,
I haven't heard of them before. Most of the denitrification filters of which I'm aware, have relied on a carbon source.
In those climates that have a year round plant growing season, the plants would take up the nitrates and so a denitrification filter shouldn't be necessary.
Thera are, however, those places (like Europe and the continental US) where they experience freezing winters and where plant growing would not be possible.....so I guess being able to denitrify the water would be a benefit in this situation.
