Hey there! I just made an account so I could comment on this..I hope you're able to see it. Does this setup still work well for you? I have a 1/15hp aquarium chiller and for the life of me can't figure out what strength of pump I should get that will be strong enough to get water up to the radiator? The sheet says 160 gph is the 'max' flow rate, but does that mean I could still get a stronger pump and not have it break on me? Thanks for any reply!
