Wave maker

[monocus]

i'm using a wp 40 on my 240-good water movement but nothing compared to a wave box(changing my wave box pump tomorrow).with the box it pushes out a couple of cups of water at each pulse and then refills.the wp is just taking the surrounding water with no real displacement.i'm not saying the wps are not any good-i'm very happy with them(i also have a wp25 in my frag tank)
