Stumbled across this forum where, in early 2012, guys were toying with the idea of using powerheads and/or water lifts on constant height one-pump (chop) systems to stay under 10 watts of power to run the entire system! incredible and very exciting. I am already wanting to tear down what I’ve built and start all over with a much better design
