Vivosun submersible water pump comparison. I've had the 310 watt water pump for a year but would only turn it on occasionally. Having it on all the time was running up the electric bill. So I decided to get the 120 watt and made a comparison video. Hope it helps if you are looking to buy one of these pumps.
