Wrong they are nitrAte /phosphate factories , while you should be changing out your filter pad monthly at very least if you have issues with those 2 perameters take it off and do a water change you will see them fall or start to fall ... I have experienced this first hand .. LR rubble is a 50/50 in a nano as you want the best water polish you can get and sometimes it is just not practical to run rubble ... some one on another site had issues even with the rubble .. I can only tell you from experince what has happened to me . Others will also back me up on this and the bio balls/rings ...
Und, glad to hear things are going for you .I wish you continued success
I have no experience with a nano so I am sure you are correct very good point. I currently have a Biowheel with a purigen pouch in it but on a bigger tank simply because I needed a place to run chemical media. I just feel as if the Biowheels or similar type filters get a bad reputation for being Nitrate factories when If you are maintaining them as needed rinsing the media and changing often they very well can be beneficial. There are many variables to the equation. I am still new at this and learning maybe I am wrong it is very likely. I am just wondering how the Biowheel by itself could house nitrates it absorbs bacteria but really does not absorb as much waste as the filter pads do to create the nitrates.
