Our tanks are nothing like the ocean...
The ocean has one heck of a biological filtration system that we could never replicate in captivity.
Probiotic systems do work, and VERY effectively. Refugiums (with algae) do work and VERY effectively. Water changes do work and VERY effectively. Protein skimmers do work and VERY effectively... etc., etc.
There are many ways to skin a cat, choose your poison, or poisons, but there's no reason to bash any means of filtration, unless it actually doesn't work... like Marc Weiss products for example.
If your interested in running a probiotic system (bacterial driven) you should understand them from A-Z along with the Nitrogen cycle in general... there's no one way to dose a carbon source that's better assuming you don't overdose or the like. If you don't want to research and fully understand how and what you're effecting, run a refugium with chaetomorph and call it day. For me a probiotic system is less equipment, no excess algae build up in my sump, no need to prune chaeto, my list goes on...
