    Good Day All,

    Need advice, got a chiller on the weekend:thumbup: What will be the best way to connect it? Dont want to use my return pump, this will slow down the flow rate? Thinking of using a seperate pump? Please give me some tips/advice.

    Regrads,

    which chiller?
    for example the haelea 500a has a recommended flow 1200-3000 LPH

    Just a hint it all depends on your overflow,
    you don't need a pump for your chiller connect it to your overflow with a control valve.

    If you do that, then the water that go's through the chiller does not get filtered. The flow through the chiller also needs to be less than the return pump.

    If you take from the last chamber and return to the first it is better. IMO

    The flow rate is 1400 to 3000 LPH. I would go for. Something in the 2000 - 2800 range.

    HC-500A

    i have my heater set at 22 as my house runs a little warm with loads of windows and direct sun, and the chiller is set to 24
    i control both through a thermostat and independant temp probe to make sure neighter can fail on

    Set it to 25c. When the temp drops below 25c the chiller will stop chilling but remain switched on. When the temp reaches 26c the chiller will start chilling again.

    If you have an aquarium controller, Aquatronica or Profilux. Then set the temp to 24c on the chiller and 25c on the controller. Then set the hysteresis on the controller to 0.2. This will keep the temp more stable than the chiller is able to do without the controller.

    Both the Aquatronica and Profilux are good. But pricy. Check out @Manic thread on a DIY controller if you want a good DIY option.

    As for the heaters do the reverse as for chiller.

    I run a return pump that is bigger then required, so I have a outlet manifold on the return line which I use to provide flow to my Chiller, PO4 Reactor, NO3 Reactor and second tank. although these devices "dump" their water bank into the sump and recirculated back through the retun pump, but as about 70% of the flow is returned to the tank, only the 30% is "remixed" in the sump again. - If that makes sense.

    But I also control my chiller with my DIY controller, so there is not a problem of my chiller kicking in and out to often because of the "reduced" flow through the chiller.
