My tank is a year old this month. For practically the whole year I have used filter socks. a person I know who's an accomplished aquarist doesn't believe in them. Sorry I can't say why because I got this info from a good friend of his. I've read where others think it makes the water too clean. In the last two weeks I've been running without one to no ill effects, yet. What do you guys do? I hope to hear both sides on this.
