External Pumps

I've got a RIO 3100 for the sump return. Should give me about 500 to 600 CFM head pressure. I'm looking to drill in for a closed loop system and just use the Korilias as is.

I hope you mean gallons per hour...as 600 cfm (cubic feet per minute) is about 269,000 gallons per hour. Crazy water flow up in that tank.

LOL. Yup, GPH is what I meant to say. CFM would be one heck of a water turnover for a 90 gal tank.
