Forgot to mention - the electric bill was pretty high too.


One of the reasons it was so high was instead of one big air pump,
I used 5 smaller ones. Next time, it would be one big one.


Come on... :-)


I cannot imagine air pumps, even 5 of them, making a significant
difference in a whole-house electric bill... What are they consuming?
3 Watt each?


Running 5 of them 24/7 would be about 5x3W = 15W, times 720
hours in a month gives 10800 Wh. With the average price 10 cents
per kWh you would pay about 11x10cents, which is about 1 dollar
and 10 cents per month, and you probably pay less than 10c/kWh :-)


I would rather look at lights and heaters, especially if the tanks
where located in a cold basement...


Sorry - forgot to mention - all the tanks had separate lights and
heaters too. And they were in a basement. If I did it again, I have a
heated room for everything.- Hide quoted text -
