Sorry for taking the thread off track. That wasn't my intention. I had to edit my post a little because I was mainly trying to encourage people to think things through, research, and then decide for themselves rather than say Dr. Ron said this or Eric Bourneman said that. I'm sorry I didn't see this post previously. I was in the midst of a huge project at work plus it's tax season.
Of course I don't think you were an idiot for not buying XYZ.com. I don't even think there is such a company. I was trying to give an anology that just because an "expert" says you should buy a particular stock, that doesn't make it true. In fact, some of those experts have been charged with multimillion dollar penalties by the S.E.C. for their bad advice. It was an anology gone bad. Sorry about that. (See the confusion that can happen when accountants are allowed to touch the letter keys instead of just the number keys
).
But back to bad advice. I originally said I wouldn't go there, but I guess I should now. I personally think that Eric is wrong and I find his reasoning questionable. Our closed systems accumulate nutrients and nasties over time. If you are running a tank for a while and intend to continue upgrading to new tanks every couple of years, maybe leaving things to accumulate will work until your next teardown. If you want to have your tank be fairly permanent (mine is built into my wall so that means it is definately permanent), I'm all for getting as much of the DOC's, detritus, etc. out of the system as possible with continuous skimming.
