Right now I have a circular flow pattern in my tank. I would like to get a wave maker, controller, some sort of random flow. What do you guys think is the best way to go?

I think it would be sweet to get somthing that similates flow through out the day, tides, low and high waves ect... any ideas? I dont mind spending a lil bit if I have to save for a lil while. I want quality

The LFS told me the tunze wave box would be too big for my 65 gal
