Powerheads

[hokedalredy]

I have a 20g tank that I am going have fish, lr, and corals when I can...I have a bio-wheel running now...I saw on here that a RIO 200 powerhead is 18.99 same for the 400 and 600. I was just trying to plan ahead and thought I would get two of the 600 since they are all the same price but I was curious if there was a way to adjust their power or if this would be too much circulation. Thanks in advance.

if you think it's too much circulation you could point one directly at the surface to create water tension and this would help diffuse some of the power.
Just a thought

I have a maxi-jet 600 in my 20 but I would have gone beyond the 600 if I can choose another one. And now I got to buy one more, so I would suggest maxi-jet 800 at least (not sure if it is 800 or what), but just beyond 600.
