Precisely that is why I said that a filter for it would be more effective. The problem is the anaerobic bacteria doesn't want that much oxygen (if I remember 8th grade science) so to much flow rate will not build a colony. Could use the PVC
trick to build the colonies so when you have the money for the filter you already have the bacteria built up. I am no expert on the subject just have done research on the nitrogen cycle and read tips on how to help your aquarium maintain 0 levels. Most of which require way to much for it to be considered a hobby. But if you like hydroponics gardens that's another way you could do it too.
