Chillers Notes

Chillers are the most effective means to cool down the water in a tank. Very simple process, the aquarium water is circulated through a “mini-refrigerator” where the aquarium water passes over the cooling coils of the refrigerant. I have seen two means of implementing chillers from a plumbing point of view. 1) A secondary pump supplies water to the chiller and circulates water from the sump to the chiller and returns it to the sump. 2) The return pump has a secondary leg cut off the primary return that supplies water to the chiller and circulates water from the sump to the chiller and returns it to the sump. In the first case, the secondary pump is only on when the chiller is on. Thus, it is possible for stagnant water to develop if the chiller is off for an extended period of time. In the second case, water is continually circulating through the chiller. The second case has the impact of diffusing the power of the return pump and the benefit of avoiding possible stagnant water.

I chose to implement the second option with the chiller tied to the return pump.
