Sunsun CSP-40 Pond Skimmer – Fresh & Salt Water Surface Debris Remover

The Sunsun CSP-40 is an in-pond surface skimmer built to keep your pond's water surface clear of leaves, pollen, dust, and floating debris before it sinks and fouls your filtration system. Suitable for both fresh water and salt water setups, it's designed for ponds up to 40m² and pairs directly with your existing pump via a flexible hose connection — cutting down on manual netting and reducing the load on your bio filter.

For koi and ornamental pond keepers, keeping the surface clean isn't just cosmetic — floating debris that sinks and decomposes is one of the biggest hidden contributors to ammonia spikes and poor water clarity.
