Bare Bottom pros or cons?

I'm willing to bet KK"s liverock contains more microfaunal diversity than you'll find in a typical SSB.
I know mine does.

Get enough crud accumulated at the bottom of a BB aquarium and the substrate (if you want to call it that) can contain more microfauna per inch than you'd find in a typical 'clean' DSB reef aquarium because populations are a direct result of food availability. (Obviously diversity will depend on what's introduced to the aquarium). This brings up another good point- most of the microfauna found in reef aquaria arrive in/on liverock or as hitch-hikers on corals, not in sand samples.
You can call it speculation but the fact remains- bare bottom reef aquaria were "in" during the early 80's. DSB's arrived later. There's many good reasons that reefkeepers have returned to running BB and to call these reasons all specualtiuon is simply not true.

I will be settting up 75 gallon sps tank, plan on using two Koralia 3s. Been reading about bare bottom tanks. Any opinions and feedback?

this thread is in regards to setting up a 75 gallon SPS reef aquarium and the pros and cons of running BB.
HB- it doesn't appear that you have a SPS reef aquarium. All the photos in your gallery are softies...
