I would install separate pump in sump and return chilled water to Main tank. In this way the main tank with fishes & corals will be cool first instead of the sump being cool first without any heat loss. This will also greatly increased the turnover of your tank water volume per hour from sump into main tank & return back into sump. I think not possible to tee off return pump outlet presumably with unfiltered dirty aquarium water from main tank to chiller. Also, a pressure pump is needed to supply higher pressurise water against the flow resistance of the narrow Chiller winding coil.
I’m keen to know more from senior and my thought is.
Way 1 - is my present connection but believe waste of energy provided if I can reuse the chilled water for another usage like through reactor, etc..
Way 2 - save energy compare with way 1 and can afford to downsize circulation pump for main tank, if one pump down you still had one running.
Way 3 - got no idea.
Bigger is not better, its just allow u more time to react if anything were to happen example power failure. Learn it the hard way previously, added too much too fast. Even with a bigger tank, need to be patient and allow the tank to mature. Once its mature, u can add stuff in slowly and u will see that all will survive.
No idea. I soaked. I washed. I soaked again w RODI water. I sunned for almost a month. Then I rinse before stariting cycle. I dose bacteria. Yet my tank not doing well. Fishes died. Algae bloomed. Don’t know what went wrong. Didn’t experience these w my Lagoon tank. N they say bigger is better
