REPLACEMENT RUBBER MEMBRANE AERATOR FOR A 110MM BOTTOM DRAIN SUMP KOI FISH POND

Aeration improves both water quality and filtration efficiency by drawing debris into the sump more effectively. Adding aeration to your bottom drain increases efficiency by up to 30%. Rising air bubbles create an uplift effect that circulates water toward the drain, improving waste and debris removal while also oxygenating the pond.
