Yes, no rios. had one burn up and kill half my livestock at one point in time, if i ever see a rio factory im gonna burn half of their stuff up
Go with a Tunze stream with controller, i highly suggest the controller if you get a tunze its like a kid in a candy store but with practical uses
Also, use MJ's for dead spots in the tank. Seios are in between. If you are about saving money or dont have the money use a bunch of mod'd MJ's, but if you got the dough, get a tunze.
I have heard the vortecs are nice, but havent used one or even seen one in person so i dont know.
