What is the difference in an "In Display DSB" and a "REMOTE DSB"
In Display, yes high flow rates. Do not want too much settlement of detritus everywhere. Where are the filter feeders? On your rock, and inside the rock. So you must keep small particles up.
Remote DSB, slow enough not to cause sandstorms and pull sand over to return pump. But not too fast, to allow some settlement. Where are the stuf that want food or detritus. In the sand. So stuff must settle.
So yes, I can see why there are so many conflicting comments. But first ask yourself, do the comment apply to In Tank DSB or remote DSB.
