I have a jbj 1/3 chiller. Planning on tieing the chiller in to my eheim 1262 return pump. Will this be enough flow going through the chiller or should I have a seperate supply pump for the chiller, and if so what would you recommend. It is 5 ft from the return pump to the top of tank. Planning on the chiller being located about 10 feet away from the tank. If that doesnt work it will be about 2 feet from tank. What would your recommendations be. Also would you go from sump to sump or from sump to tank.
