Oxygen equals Life. This is all the more true in a garden pond. A well aerated garden pond will feature less algae, healthier fish and clearer water. Good pond aeration helps filtration processes, improves the water quality, prevents the pond from becoming stagnant and helps fish to breathe, particularly in warmer weather when the dissolved Oxygen in the water is even less.
