Interesting, thanks for the post. Sounds like what most people here have been saying -
LR, LS and skimmer = healthy tank. I also read the guys post about no water changes, didn't he say he had lots of
LR? I would bet that there is an achievable balance between bio load and live bio filters where manmade filters would not be needed. But I would think a certain amount of trace minerals/supplements would be needed. So much to learn...
