Carbon is such an important element in most everything organic I have trouble understanding how it could be detrimental. I'm not criticizing anyone, just confused. Carbon has been used to filter aquariums, drinking water, swimming pools, etc. for many years and I have never before heard of a negative effect. Does anyone know of any studies?
I agree that good filtration, water changes and not overfeeding or overstocking will pretty much eliminate the need for charcoal. With good maintainence, in my opinion, it does become redundant. I use it in my diatom when there is a specific need. I also do a much smaller volume of water changing in my aquariums than is regularly mentioned by hobbyists and my fish and plants seem pretty happy. I'm not going to win tank of the month any time soon but that, in my case, is more of an artistic thing.
