So I have some black diamond hybrids and I know their from river systems but I was wondering how much water movement do they like? obviously I have a power head in there but It’s only does 950 Gph, plus the filter that pushes lots of surface water around, it’s a 250 gallon But I have an extra 1250 gph that I’m not using, I guess my main question is should I put the extra powerHead towards the bottom of the tank on the same side as the existing powerhead and the intake and push all that water to the outtake on the other side creating a nice current at the bottom of the tank, (it’s bare bottom )
