PreFilter Sock 4" (200 micron) Short

The Eco System Pre Filter Sock 4" Short is an effective mechanical filtration solution designed to remove suspended debris and organic waste before water reaches your sump equipment and return pump. By capturing particles at the first stage of filtration, it helps maintain cleaner, clearer aquarium water and improves overall filtration efficiency.

Ideal for both freshwater and marine aquariums, this filter sock efficiently traps uneaten food, fish waste, detritus, and other suspended particles before they can break down and impact water quality.

Features:

• 200 Micron Filtration - Designed to capture larger particles and organic debris while maintaining strong water flow.

• 4" Ring Diameter - Fits most standard 4-inch filter sock holders and sump filtration systems.

• Compact Short Profile - Ideal for smaller sumps, shallow filter chambers, and installations where space is limited.

• Improves Water Clarity - Helps remove visible particles before they circulate through the aquarium.

• Length: 21cm

Regular replacement or cleaning of filter socks is essential for maintaining optimal water quality. By removing trapped organic waste before it decomposes, filter socks help minimise the accumulation of nitrates and phosphates that can contribute to unwanted algae growth and poor water conditions. Consistent maintenance also promotes clearer water and supports a healthier environment for fish, corals, and other aquatic plants.
