compared to SS's i would get an OM unit WAY before i would get one of those. just because you can pack so much more flow through the OM unit and if something breaks there are minimal parts to repair which you can do yourself unlike SS's
compared to a tunze wave box...not sure...never used one. the cost factor will plany into this, hiding the tunze wavemaker, heat from pumps, electrical cost, etc. but in a tank my size i can't do a wavebox.
i will not own another tank w/out an OM unit if that means anything
Has anyone really thought about how those things work? Or what they work like I should say? I like those corner box things that suck water up through the bottom and gently push it out all the way up till it hits the top and then it agitates the water surface. Whatever they are called.
