To be fair are you talking a "wave box" or a "wave controller" big price difference. Them you'd need 2 Tunze power heads...
Mp10 comes with everything you need.
The mp10 will give you numerous modes, a cleaning mode(it just helps kick up debris before water changes) it also lets you set the percentage of power from 10% to 100%. You can also set up the night time mode where you can have the mp10 slow down kinda like making the "ocean" calm at night.
Another thing with the mp10 is the "dry" side has the motor so no heat issues. The "wet" side is the propeller.
I'm sure the Tunze wave box or wave controllers are good products but I can't speak on them as I own a mp10 and I'm very happy with it.
I did however have a Tunze 9002 skimmer for my BC29... I later found out it couldn't fly.
