Hi All. I have a hailea 1000a chiller using for my 60gallons reef tank. Current I have a 3500 lph pump for the chiller. It takes 40 minutes to cool the tank to set temperature. I think I need a lower flow rate pump, so there is more contact time with coil in chiller. My question is, What flow rate pump shall I use with my hailea 1000a chiller? Is 1500 lph flow too low or just perfect? Please help!
