ok to void the other 2 post. when i thought i got it but i guess i didn't. but now i do.
turnover - volume entering and exiting tank
flow -
gph in display only
so i guess instead of one big mag 36
i'll get 2 smaller pumps maybe 2x mag 12 and use one for return and use another one for a closed-loop/manifold (is manifold another word for closed-loop?) and get the flow i will need in the future.
again drawings coming soon for critiques.
