1 or 2 Nano 6025's in 40g???

So the 600 gph flow is deceiving because the flow is so dispersed? I would think 1200 gph flow would be too much for the 40... Thoughts?
 
i think you are better off with 2 small ones rather than one big one... i think 2 6025 will be perfect for your 40... you can also go with 2 6045 depending on what you're keeping, but unless you're a flow hog, that on the very high side...
 
i would maybe get a coralife power center or reef fanatic wave creator to switch them on and off every 15 minutes for some nice random flow.
