F&W, My utility bills are shameful. My goal for this year is to bring them down. What I spent so far to develop thi thing is also rediculous, just ask my wife. I could duplicate it now for a reasonable amount. The new drum filters have really reduced filter maintenance. They should they were expensive but I can now leave for a week at a time and they run on their own. My fish are a all male population. mixed sex and different size fish in a system like this are not good. Thanks for the interest, Steve
