Aqua Nova NUB-9000 Complete Gravity Pond Filter with 11W UV-C

Aqua Nova NUB-9000 is a complete gravity pond filter designed to maintain cleaner, clearer water in ponds up to 9000 L. It combines mechanical, biological and UV-C treatment in one practical filtration unit, helping to remove visible debris while supporting the natural processes that keep pond water healthy and balanced.

Water passes through two types of filter sponge, which trap solid impurities such as plant fragments, fish waste and uneaten food. The supplied filter sponges and bioballs provide a broad filtration area, allowing beneficial nitrifying bacteria to establish and help process harmful nitrogen compounds. This multi-stage process makes the filter suitable for everyday pond maintenance and helps reduce the build-up of organic waste.

An integrated 11 W UV-C lamp exposes the flowing water to ultraviolet light, helping to control free-floating algae responsible for green water as well as unwanted microorganisms. The filter can be partially buried to blend more discreetly into the garden, while universal 20, 25, 32 and 40 mm inlet connections make installation flexible. A suitable circulation or fountain pump is required and is not included.
