Re: Quick denitrification

Hi Paul 

I'm generally a lurker...but I find your post very interesting, esp around
the 
denitrification process using dried liver.  You indicated that this method
might 
increase the ammonia. Therefore, assuming that you have a normal nitrifying 
filter in place (eg canister, wet/dry...etc) that would take care of the
increase 
in ammonia levels, and end-result in again NO3 production. So, wouldn't 
having a normal nitrifying filter and a liver-denitrifying filter in the
same tank just
result in a vicious cycle. 

Just curious...

rgds,
Roy
