RSM 250 Upgrade Pumps and Skimmer Advice

[RipCurl]

I am wanting to upgrade my stock RSM 250 pump. I would like to increase my flow rate in my tank and also have pumps thats generate less heat than the stock skimmers. Anyone out there upgrade their pumps for increased flow and less heat? If so, what pumps fit/work for this upgrade?

The same goes for the sotck skimmer. I would like to upgrade to something that fits and is easier to maintain and regulate.

Any insight would be GREATLY appreciated!!!

THANK YOU
