I use tap water run thru my faucet water filter. I usually fill a gallon jug 1-2 days before my scheduled watering day. Today i added some mollases and on a whim hooked up an air stone and air pump to help agitate and mix the molasses and water together. It started me wondering if the oxigen mixed water would be a benefit to my plants on its own or am i just spinning my wheels. Since I let the water sit for a day or 2 i figure it is probably pretty flat.
