you will want more flow for sure! i have two K4's in my 50. i didn't like the low flow so i went online and got the sureflow kit that they use on maxijet. this kit came with two props a med flow and high flow. it only cost 15 bucks so i thought i would try it. they work great with awesome flow. the only down side is sometimes i think the power flickers or something cause one will go backwards sometimes. but for 15 bucks awesome flow!

and i will be redoing my aquascape and should have some rock to get rid of.....one of these days.
