Suggestions Needed On An External Pump

[msebar]

My build is a 180g planted with co2 (2 overflows) with a 55g sump. I don't want to use a submersible as it will add heat to the tank. I was looking at the Little Giant 4-MDQX-SC which is 1325gph - 1225ghp at 3 feet and 1080gph at 6 feet. My lift would be less then 5 feet. This would give me a turn around rate of 6x. The watts on this baby is 135w. I found the pump for about $225.00 including shipping. What are your thoughts and suggestions.
