Increasing filtration is one of the most effective methods to remove green algae from pond water. First and foremost, you should already have a three-stage filter that employs the three main types of filtration (mechanical, biological, and chemical).
It is a waterfall, streambed, or series of waterfalls that cascade into a stone-covered, concealed reservoir. A pondless water feature is an excellent choice for busy householders who desire the sound of running water without the upkeep of a pond.
Replace outdated infrastructure and potential sources of lead. Replace galvanized plumbing with copper pipelines and install "lead-free" plumbing fixtures containing no more than 0.25 per cent lead. After installation, purge cold water faucets daily for three days for five minutes.
Fertilization increases the concentration of naturally occurring nutrients, such as nitrogen and phosphorus, in the pond. Together, these nutrients sustain this desirable algal bloom and the subsequent biological productivity at all levels of the ecosystem.
