Eric Borneman's November 'Coral Whisperer' article has got me wondering.
If anything, I guess it's an argument to maintain doing water changes, running activated carbon, and possibly even other resins (Is 'ChemiPure' using bentonite, what Eric mentions is an 'activated clay'?)
Anyways, it's sure got me thinking.. Wondering what other people's take on this is.
