I'm going to buy a Rio 800 RVT toward the end of the month to replace the 180 currently feeding my CO2 reactor. I'm hoping the irregular surfaces of the new impeller design will add a little more chopping action without a mod. My tank is in my living room as well, so noise level will count. I'll let you know how it turns out.
