Creating a good reef current

[philly]

i was looking at revtrees and landos tank pics, very nice by the way, and i realized one big equipement difference bettween my 90 gallon tank and their tanks. you cant see the equipement that moves the water around in their tank. i have 4 ugly hagen 402 powerheads. i want to get rid of them and gett watever those guys have in their tanks. it has to be good for corals like xenia and gonipora, not direct current but still makes them pulasate. I need recomendations. tanks guys. not that expensive under 200 canadian dollars.

thanks guys
