Well I have used rio, and hagen powerheads, ehiem and rena inlines. The rio is on ok pump but is is only ment for using submerged. You will need to get a container for a resevore to run it in. All powerheads like the rio, hagen aquaclear, maxi jet, penguins, etc. have to be run submerged thats how they are cooled. If they are not run in this way they will die within a very short amount of time. As for setting it up go down to your local hose shop and just keep testing out different fitings till you find the ones that meet your needs. Look at this for more info on it.

One last word I'm not trying to put them down but they will run warmer than an inline system but to be fair all powerhead pumps suffer from this same problem. On my system I noticed a 2c temp rise by using the rio over my ehiem. Make sure that you have a good radiator or you will notice more that 2c difference in your temps.
