Hi just wondering if anyone knows how much electricity my 30L biorb tank i dont use a heater as ive only got temperate fish pets at home says its a 12V usage tank and the pump is 2W
Sure. If all you use is the 2W pump: Price cap for a a kWh of energy right now is just less than 25p. A 2W pump ran for an hour would cost you 0.05p. 24hours is 1.2p. So worst case scenario £4.48 a year.
I assume you also have a light. Let me know what power it is (W) and how long you have it on for and I’ll tell you how much that costs you too.
