Magnetic "seio"

[Willow]

guess it all depends on what’s your goals for you tank is, what you want to grow and how seriously you take this hobby. if you were growing softies and zoos then you wouldn’t need one, if on the other hand you have a 220 gallon tank and are growing sps you need a lot of water movement.

the pump moves a max of 3100 gph.

tunze is not distributing the pump, tunze is their competitor.
