I used totes and a reservoir outside the tent with a chiller. Pump recycled the water through the system. Worked nice. Just it was summer, the heat, yada yada. I grew tired of the daily tending of the system.Goin to try something different and not waste so much water. Cleaning and refill was a task when things went south. I don't relish the idea of doing it again. So my current setup is now 2 2x4 tents and I am learning how to succeed with autopot system. Its not as easy as they say there is a learning curve to get them to work at peak performance. We will see how it goes and I'll share since finding info on these systems and folks who use them are primarily in UK
