I am now really motivated and set on aerating my pond when we get back from the US. Can anybody shed some light on what would be the best value for money option? and approximayely how much will it cost to buy and get back to OZ? Oh and my neighbors back in OZ have put their cow and calf into the padock, is that going to cause a major problem? It is a new pond and vegetation is just starting to take on the dam walls. (The cows have to swim occasionally because it is over 100 F at the moment)
