| Like everything in this hobby this is all based on opions and personal expierence. Every tank is different and works differently. I have had succes with the same DSB ( mines only 3-4inches at best) for over 3 years now. I even moved it once and added more sand about a year ago. If it ain't broke to fix it ( just watch it) is my motto.
