more impress with evo1050 than mp10

[geaux xman]

I've had both on my 29g QT tank. the koralia is quiet and you can better control the flow direction. i have it midway on the leftside and pointed up.... getting plenty of surface water agitation. the mp10 hums pretty loud.

paid 22.50 for the evo1050 brand new from big al's with a discount.

the vortech allows for no cords in the tank, which looks much better imo. no heat being added from the mp10, and the mp10 comes with a built in controller, the varied flow is much more beneficial than a constant speed imo. if the noise is an issue you must have a very quite tank, because i'm 2 feet from my mp10 and can't even hear it. also, there is no way the koralia undertow can compare to the vortech
