Pond Aerator Ring 25 cm with 3m Air Hose for Koi Ponds

Pond Aerator Ring 25 cm with 3m Air Hose for Koi Ponds 25 cm double-ring pond aerator with 3m 8mm hose and non-return valve; for 25-30 L/min pumps, pump not included

The Zolirao 25 cm pond aerator ring is designed to work with a compatible pond air pump to create a broad circle of bubbles in ponds, tanks and filtration systems. Its double-ring layout helps distribute air across a wider area than a single outlet, making it suitable for koi ponds, garden ponds, aquariums, fish tanks, hydroponic reservoirs and moving bed biofilters. The set includes a 25 cm double-ring aerator, 3m 8mm air hose and a non-return valve. The porous rubber diffuser tube releases bubbles around the ring, while the weighted metal design helps the aerator sit at the bottom for steadier use. For best results, use with a compatible air pump rated 25-30 L/min or above. Air pump is not included. Please check your pump outlet size and airflow before purchase.
