GCTEK AlphaNano Pond Bead Filters

The GCTEK AquaNano Pond Filter is a high‐performance bead filter designed to deliver exceptional mechanical and biological filtration in a compact, energy‑efficient package for koi ponds and water gardens. Using GCTEK’s advanced AlphaNano media, it provides a very high surface area for beneficial bacteria, allowing fast breakdown of fish waste, ammonia, and nitrite while polishing the water for outstanding clarity.

Inside the AquaNano, lightweight bead media is fluidized and evenly distributed so water contacts as much media as possible, boosting filtration efficiency while keeping operating pressures low. This design lets you use smaller, more efficient pumps than many traditional bead filters, saving on energy costs over the life of the pond. Routine cleaning is handled through a simple backwash cycle that agitates and lifts debris off the beads, making maintenance quick and user‑friendly for both hobbyists and pros.

AquaNano filters are available in multiple sizes to match a wide range of pond volumes and fish loads, using the same core media and hydraulics across the line. Larger models in the family can handle heavily stocked koi ponds with high flows, while smaller units suit modest ornamental ponds that still demand top‑tier water quality. Heavy‑duty, corrosion‑resistant housings and quality valves round out the system, giving pond owners a durable, long‑term filtration solution.
