I think you should go for it. I will be buying another one soon. I had one on a 90g with 2 Oscars, Lima shovel nose and 2 plec's and my levels were always good.
I know someone that has one on a 28 euro with 12 4-6" goldfish in it and doesn't have any problems. I am getting the H.O.T. next week because I have heard they are really good at polishing the water, and that is what I need.
