Testing this rechargeable airpump I got from Amazon for 12 bucks. The thing turns on when it senses power failure. I can plug it into my kasa power strip usb port. It wont take up any outlet space! It also has intermittent mode and space for 2 lines. I think this thing is amazing. I want to run it down the inside of the weir so its not visible and poke it out one of the holes to hide behind the rockwork. Stay tuned.
