I got a Tunze 6025 today. It is an awesome powerhead. It is the first one that I've had in my tank and I can already see the difference in the well being of the tank. It will probably take a few days for all the sediment to clear out. There was some stale waste sitting on the tops of rocks and on the sand bed.

Now I just need to fiddle with it until I find the right place for it.
