Well, sorry to disagree with you, Albert. But I have had gobies, and not had gobies. When I had a goby (Orange Spot Sleeper), never (and I mean never, ever) had algae on my sand, and it always looked pristine white. When I didn't have a goby, in a short time, the sand would lose its pristine color (more brown at first) and eventually algae (the aggressive green stuff would start in). I could keep it clean with vacuuming, but that was extra work that just wasn't required with a goby.
Of course, a Goby is not majic, and does not get rid of your P04 and N03. You need GFO and biopellets for that (or some other equivalent regime). But even with zero P04 and zero N03, and no goby, my sand would still look like crap, unless I vacuumed it.
Nothing against BB tanks as such, but for those who prefer sand, there are ways to keep it clean and pristine looking, without a lot of work, ie get the goby.
And conversely to what you said, Albert, BB does not magically solve your other water issues either. You still need a good skimmer, good flow, and a regime to get rid of your phosphates and nitrates.
