If the analytical tests are correct,,, your N:P ratio is low. The Good ratio for producing a good bloom of green algae is said to be around 20N:1totalP (best range 14-50:1). Redfield Ratio. Your ratio is 2.6:1 (1.1ppm/0.41ppm) which indicates to me your pond is what we call nitrogen limited. Nitrogen is too low for producing a good bloom of green healthy algae.
