I bought an air pump for fish farming. The label on the air pump is 220V. May I ask how much you use the gas pump for an hour?
Take a look at the power. For example, one thousand Watt, that is, an hour of electricity. Five hundred watt is two hours a kilowatt hour. That should be very small
Fish with a small pump power is small, it is estimated that more than a dozen watts ---- dozens of tiles look.
Power watts or current safety shall be marked. Estimated number of watts. Such as 50 Watt, open 20 hours, once electricity.
