Trust me your sand isn't dead!
Often times it is an experiment to find the exact location that works for your particular tank based on a number of variables, such as number of pounds of live rock and how it is situated, coral species and number, tank size and design and powerhead number GPH.
I have very fine aragonite sand due to my Tridacna Clams, Conch snails, various corals and Sea Cucumbers, so I know what you are talking about in terms of stirring up sediment and sand all over your livestock.
Your best bet is to diffuse the water flow by banking it ff your glass to disperse the flow to a great area and also reduce the chances of laminar flow and problems with stirring up your sand. _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.
