Hi,
in the past, i use this pool filter for a little pound.
and my
"little giant pump" was enough powerfull to make it.
of course that was not an impressive flow... but i could do the backwash and have a little watterfall etc...
the goal is to have "just one filter" and 1intake/1out take
of course i will buy a more powerfull pump for it...
may be 3 time my little giant... don't really know for now
(i can't really estimate what kind of restriction that sand filter will do...i have to test)
i think that someting like 1500-2000gph "real" will be good.
may be this
pump ?
anyway i will not use a pool pump
the tank is "in the wall" and i have a room juste for it.
thanks !
