I'm just trying to figure out roughly what my tanks cost per month to run and wondering if anyone might know the answer...
Here's the break-down:
2x - 2w Air pumps
3x - 15w Lights (12hr program)
2w Moon light, (12hr program)
100w Heater, I'm guessing is only on half the time...
300w Heater, same as above
5w Filter
8w Filter
by what I've calculated by dividing the usage of the heaters and lights, I came up with 223.5w, so if this is correct what would my monthly cost be?
