i have been reading alot of about these power heads for the past 3 months .. it has been getting really good reviews so i thought i would look into them .. they are the jebao WP40s .. for the price well worth looking at and into .. i put just 1 on my 180 .. everything is moving in the wave it puts out .. it has 5 different settings .. i use the W1 with the dial turned to the left pointing at about 10:00 .. this thing is a beast of a pump .. i have no other pumps on my tank right now .. removed all my power heads to see what it would do .. heres a lil sample video of it ..
