chiller on Return Pump, or seperate?

[wiszmaster]

I have a 1/2 HP chiller (barrel) that i need to hook-up.

Question:
Run it inline, on the regular return pump, or do i need to get a seperate pump from the intake of the sump & dump it back into the sump right before the end of the sump, where the return pump takes te water back to the tank?

tank:
150g

sump:
100g

chiller:
1/2 HP

return pump:
Little Giant 4-MDQX-SC (~1950GPH @ 6ft)


i doubt i'm putting that much flow through the pump though ... i have it going from 1" outlet right down to 3/4" for the return of my tank.

would this flow be OK, or is it too much to be effective for the chiller?



Thank You,
