- I hear people that they hear noises coming from reactor... is it really noisy? May be noise is only when CO2 is being injected, or noise is from water flow? My aquarium is in bedroom, so it is important for aquarium stuff to work quiet.

1.I'd run 200gph or so
2. No, not much. Work on making the inside of the stand quiet also(padding, insultation materials, rubber etc).
