I have an EV400 and I love this skimmer. When I was thinking of getting it (I got a good deal on a used one) the only downside people said was the electricity to run an extra pump. I run my with a mag 12. I like the simplicity of it too. It just shoots the water at a high rate of speed down an angled plate. Try to get the extra collection cup if possible, its nice to have, gives you a little more time between cleanings. And when I clean it I always leave a slight film in the main tube. This way it can get to the top a lot faster. Good luck with your tank!
