Are you referring to the aquariapure system? or something similar? I had read one of the advantages to those are less water changes, but by less are we talking once every couple of months? My nitrates generally stay at 0 or right at it so I kind of put this system "denitrifcation" to the side thinking I didn't really need it. But if it really does reduce them as much as advertised I may have to revisit them.
Also, i came across a guy not to long ago who was purchasing a tank from me and he said in the year he has had his 180 gallon up and running he has never once done a water change. He basically chalked it up to having macro in a fuge, didn't really explain to much more. However, he didn't strike me as someone who didn't know what he was doing as he has 7 tanks up and running in his house and has been in the hobby for 15+ years. Wonder if he was using something like this to reduce or even eliminate water changes altogether.
