Just saw this from that article you posted...
"I never clean the wood or rocks in my tanks, and I am sure quite a few people would find my tanks quite dirty with all the algae and moss growing over things, but I like it that way, and I like to think my fish do too. For bacteria there is no difference between living inside the tank or inside the filter! So even when I throw out all of my filter material, I make only a small dent in the bio filtration capacity of my tank."
I wouldnt like that haha i want super clear water.
