Sorry Ian, you misunderstand the article (or maybe you misunderstand what I was referring to). The article references continuous water change, as in you're removing old water at the same time as you're pumping new water in, not daily water changes.

I was referring to daily WC where the total WC volume is removed, then consecutively replaced. Since every time you do a WC you're removing a portion of the new sw you just put in yesterday it is less effective. If the OP chooses to do daily AND continuous WC (which could very well be the case If he's using a doser for it) that would compound it by another 4%.
