whats you flow?

[fkshiu]

Tunze 6100 (~3,000 gph) alternating with a modified Tunze 6055 (~1,800+ gph)
Eheim 1260 return (~250 gph after head loss etc).
Wavebox

So at most about 3,250 gph of "primary" flow at any one time.

120 gallon display = ~27 times turnover.

Mixed reef on a Gyre flow pattern.
