The presence of algae is the bane for any pond keeper because it results in loss of fish life and depletes precious oxygen. But, with a few simple and precautionary steps, you can control algae in a pond and maintain the tranquility of the garden.
1. Maintain the Ecosystem by Adding Floating Plants
To achieve a fine balance naturally, cover at least half of the water surface with floating plants like water lettuce, azolla, water hyacinth or duckweed. Apart from these, you can even add lotus or lilies. These plants multiply quickly and work as shade for the life beneath. The submerged plant like hornwort keeps the water cool and blocks excessive sunlight and keeps the algal growth at a bare minimum. Adding plants is a necessity because they compete with algae for dissolved nutrients.
2. Love Fishes? Do NOT cram them in one pond
Who doesn’t love to see fish roaming around in crystal clear water? But, ensure that you do not add them in excess in one pond. More fishes would mean more waste (through excreta and food) which would result in the fast algae bloom.
3. Keep Debris at Bay
For algae control, regularly clean the water surface with a pond vacuum, net or with AquaClear Pellets. Because when these dead leaves, debris, and sludge break down, they result in the growth of algae.
