Foam Prefilter 4-Pack for Tetra Pond FK3 26594 Filter Fountain Kit

Description

Product Overview

This set of four black foam prefilters is specifically designed as a direct replacement for the original part number 19016 in Tetra Pond FK3 26594 filtering fountain kits. Each prefilter measures precisely 3-3/4 inches long by 2-5/8 inches in diameter with a central 1-inch hole that runs through, ensuring perfect alignment and fit within the existing filter housing. Made from dense, high-quality foam material, these prefilters are engineered to capture debris and particulates effectively without clogging or restricting water flow. The compact size (1 x 1 x 0.5 inches) and lightweight design (0.88 ounces each) make them easy to handle during installation and maintenance.

The simple drop-in design allows for quick replacement during routine maintenance, making it suitable for both novice pond owners and experienced hobbyists who value convenience and reliability.
