You can use powerheads for flow, just DONT USE RIO's i had one pop in my first tank and kill almost everything. I would use a iwaki pump for your sump and a couple 3-4 Moded maxi jet 1200-1400's. There really isnt a need for a wave maker per-say when your on a budjet, it would be an extra cost. The maxi's are effective, low cost, low watt, and very durable. On the sump pump, you can get away with a cheeper one like a mag drive 18 or larger, lots of people sell'em for real cheap here on RF. IF you dont have holes drilled in your tank, you will want HOB overflow box, (Which i have one From my old 125 Available).
Is your tank Drilled for overflows?
