Cost of Running Our Reef

[SeaHorse_Fanatic]

In the summer, with all the heaters unplugged, my calculated cost for all my tanks, freshwater and saltwater was around $35 or so. I know we have very low hydro rates in BC, but I'm kinda shocked when I hear or read about other people paying $80-100+ for their tanks' powersupply every month. Our hydrobill doesn't even total over $50 monthly. Must be those reefers with the 400w MH (max. I have is 175w) and big, power-hungry return pumps.
