Should I try to kill off an algal bloom in a Yabby dam?
Trying to kill an algal bloom (green water) is really “treating the symptom rather than the cause.” The cause is too much nutrient, or fertiliser in the water which is usually due to pollution from a summer flood (see below). As noted above, killing off the algal bloom will drastically reduce oxygen levels for a time and the nutrients (stored in the bottom mud) will soon be recycled to produce another bloom.
