Cutting back flow of Eheim 2217
My 26 Bow is is planted in black sand.
My 2217 is a monster - and I love it. I've tried re-directing the flow, using a spray bar, no bar, etc... the bottom line is I'm pushing sand all over.
What is best practice to reduce the outflow of the filter into my tank - dial back the large in-flow tap, or dial back the out-flow tap? Or a little of both?
I'm sure the impeller is designed to move water at X RPM... so I'm thinking of dialing back the larger in-flow tube so I don't restrict the output of the impeller.
But what do I know.
Any knowledgeable suggestions are appreciated.
