Yes, but I just wanted to clarify for sure if he meant to get a 750
gph pump or get a pump that would produce 750 at the top of the
biofilter/falls. Because with the travel (horizontal/vertical) of the
hose from pump to filter, it seems by the time that happens - there
would be about 400 gph going through the filter.



I think he's saying you only need
a 750 gph for the biofilter and then get another Bigger
pump for the waterfall.
