I have tried a LOT of powerheads.
Koralia Magnum : cheap, very quiet, low energy use, but tend to die in a year or less.
Koralia Gen3 : Very low flow for what is advertised. Clog easy. Avoid.
Tunze : good, expensive, not that power efficient, quite, very adjustable direction, very reliable.
Rossmont : Noisy, and seem like flow is lower than advertised, but not bad.
MPxx : Nice, but you cannot direct flow, and you must carefully align wet/dry sides.
Gyre : Nice, but noisy. But I had an early generation, supposedly quieter now.
Jabao : Cheap, slightly noisy, but pretty good in general.
So my general suggestion: Tunze
