I am designing a 72kL marine aquarium system. The water needs to be circulated 8 times per hour and thus requires a flow rate 160L/s. I want to use sand filters so can anyone please recommend a size/quantity/supplier as well as a heat exchanger that would ensure the water temp stays around 18 degrees C. The whole system is set up in an air controlled room with avg temp of 24 degrees C.
thanks.
thanks.
