I have one running a large air-stone and one running an air curtain in my 850 ltr discus tank. The power adjustment on the top works well if you need to reduce the flow. Good solid build qaulity. I'm in the process of switching my other tanks over to these Fluval Q2 air pumps

The pump is controllable,powerful,quiet & if a y piece is added with non return valves you can have 2 air stones running at the same time,quality piece of kit!
