The cost of running a reef tank - measured

Doing a little math to see what it costs to run my tank...

3 MH bulbs - 900w x 6 hrs per day
2 VHO bulbs - 187w x 11 hrs per day
Return pump - 141w x 24 hrs per day
3 Vortech pumps - 63w x 24 hrs per day
Calcium Reactor - 65w x 24 hrs per day
3 Fuge lights - 62w x 8 hrs per day
2 Skimmer pumps - 116w x 24 hrs per day
Prop light - 147w x 7 hrs per day
2 Icecap Fans - 12w x 7 hrs per day

All of the above runs 19.3 kWh per day, or 579 kWh per month.
Take that number times $.124375 and it adds up to $72 of basic operational cost.

Not included are a handful of tiny pumps running the suncoral tank, phosban reactors, flow in the prop section and refugium, which is probably around 100w for about $9 a month more, which puts the tank at $81.
