Hi Hendre...

I'm Francesco from Rome, Italy.
This is my very first time writing on the list too!

I can't really see why a trickle filter should burn nitrate 
better than ,lets say a cannister filter...
They both work through aerobic bacteria that process aquarium
waste mainly in nitrite as a first step, then in nitrate.
But to process nitrate into something else(ammonium gas for example)
you actually need some kind of anaerobic media since the process
is done by anaerobic bacteria.

Why anyway are you so concerned about using trickle filters?

What i know for sure about it is that is going to oxidate
faster all your exepensive fertilizers.
