Maxi jets are way better than Rios, but I agree with Viper. A 180 is a pretty big tank for just a couple of Maxi Jets. I've heard great things about Tunze Nanostreams for a tank that size..

A 180g is pretty big for even a few 1200s though. I would suggest you look into a vortec, tunzes, or koralias.
