wavemaker

So, I am new to the bobby and recently got a 29 Gallon tank. I bought a Sunsun JVP-101 (800 GPH) power-head. Is that too much flow for that size tank? When its on I see the surface of the aragonite sand move a little. I also don't think the filter that came with it is strong enough, any...

I was wondering if anyone has ever owned or even heard about the blue line tsunami wave maker??? I have the chance to get one for cheap..I can't find anything on them. Can use any help I can get.
