Deep Sand Bed

[syncro]

I really liked a shallow bed in the display tank and deep bed in a compartment in the sump

* DSB gets ugly along the glass b/c exposed to light
* Easier to replace the sand if you ever want to
* Found it better than equivalent volume of live rock for keeping nitrates down

I also ran a DSB in the display for 3 or so years. Was always worried about disturbing it / releasing deadly gases but it never happened. It has been a while, but I think I replaced portions of it over the course of a month to try and solve an issue. YMMV

My "DSB"s was probably 5" deep so might be on the shallower end. I have a smaller tank so couldn't go much deeper than that.
