Determining how many air-stations/diffusers I need
To do this you’ll first need to identify your dam’s shape. There are 4 typical dam shapes: (1) round/square with no islands, (2) long and skinny, (3) dams with islands and (4) figure-eight shaped dams. Which shape is your dam most like?
In the above shapes, the dots indicate where air-stations (diffusers) will typically need to be placed to sufficiently aerate your water. This is because of what we call the ‘zone of influence’ where the circulation of oxygenated water is hindered by banks. This should give you an idea of how many diffusers you’ll need.
Determining how much hose I need
To work this out you’ll need to draw a scaled map of your dam and place a dot at each of the air-stations/diffusers. You’ll also need to know where you’re setting up your motor. Measure the distance from each air-station to the motor. Add up all the lengths and add a little extra in case your map measurements were off. This is the length of hose you’ll need.
