im still voting this way.. you'll have a lot of one directional current and will be safe

and u cna still setup the sump to have fresh water brought in, at any rate you like

i understand streams have decent water movement, but have u ever gauged what that speed is? its actually not that fast, the problem with streams and what makes them seem so fast is the VOLUME of water.. that's what gievs it that pulling feeling

also not, most fish that inhabit these streams have huge rocks or roots to hide behind to allow their bodies to rest, your flow is going to get bounced around a little, no matter how you go about it
