I have a Tunze stream 6060 on a 4' x 2' x 2' tank (120 gallons) and I think it is too much flow. There is a mix of hard and soft coral frags in the tank. There is no quiet place in the tank to place mushrooms etc, my green hairy mushrooms got blown all over the tank despite being super-glued down. Maybe I should downgrade to the Seio.
Well just ordered the Seio from Jason and hope it works out better than the stream.
