Shoving tank temperatures down sans chiller
Hello all! This spring I am considering getting a container pond and the magnificent Macropodus ocellatus to inhabit it for the 'warmer' months (otherwise known as 'the time that the water will stay liquid'). During the winter I am pulling them indoors...which is why I am writing this post. M. ocellatus needs a wintering period in the low 50's or lower for a couple months, and I'm not sure whether their soujourn outdoors (which is unlikely to last past November or before April...I'm in zone 5) would give a sufficient cooling period, so I am looking for ways to push a tank in a room in the low 60's another 5-10 degrees cooler. Any suggestions? Evaporative cooling seems the most effective at this point, but I am looking for other ideas to supplement this or specifics on how to use evaporative cooling. Thankx!
