also note there is a different in turnover and in current.
you want 10-20x in current, not really in turn over.
turnover includes water that leaves your system and goes to your
sump, then back up, but does NOT include anything contributed by power heads,
skimmers, or closed loop systems.
current includes everything in a tank that moves water.
the two can be very different and may need to be set very different, for example you may have a display tank that need about 25x in current, with a
refugium attached. obviously for the
fuge to work well you want to keep the flow low.
so you will have a display with 25x current but only 8x turnover *8x is what foes to the
fuge)
