hey guys, its been a while and i have alot of detritus build up on the rocks and parts of the sand. I have 2x hydor koralia 1400gph and a 1400gph return so probably around 800 gph when you factor in height.

Is there a way of figuring out how to get correct flow instead of blasting away with random flow, what is the objective of the flow? Any rule I should watch out for?

Its a 150 gal + 40 gal sump.

Any help?
