Monthly cost to run a tank

[asylumdown]

I just finished running the power meter on all the various power bars hooked up to my tank. Here's the results:

My 8 radions are collectively drawing 8.9 kWh of power per day

The power bar that runs my return pump, skimmer, and various other powerheads draws 6.14 kWh per day

The power bar that runs my heaters, reactor pump, and a couple more powerheads is drawing 4.77 kWh per day.

In total, my tank is drawing 19.81 kWh per day, or 594.3 kWh in a 30 day month. Our last month's power bill switched rates half way through, so taking the halfway point between the two rates ($0.085/kWh), my tank is costing roughly $50/month in electricity to run.

I have to say I'm surprised by this, I thought it would be lower. I'm going to have to look in to ways to get the total draw down. I might have to consider removing two of the radions.
