I'm trying to get the pump figured out for my system. My FT will be 4' x 8' and filled to 3', which calculates out to 718 gallons. In addition, my initial 10 GBs will hold 290 gallons of water, after accounting for the gravel. That's roughly 1,000 gallons total. If I understand correctly, I want the GBs to cycle twice an hour, so I'd need at least a 2,000 GPH pump. Can somebody make a recommendation for a pump this size?

I found a Wayne RUP160 1/6 HP, 3,000 GPH Oilless Submersible for $49.12 at Amazon, which seems pretty reasonable, but don't know what specific features I should be looking for. TIA
