What Evolution Aqua does

Evolution Aqua is a UK-based designer, manufacturer, and supplier of water filtration products serving the pond, aquarium, and commercial aquatic markets. Founded in 2001 by Nick Jackson and headquartered in Wigan, the company serves both hobbyist customers (koi and garden-pond keepers, aquarium enthusiasts) and commercial operators including fish farms, public aquariums, and commercial swimming pool facilities, with global distribution.

The company's core technology is moving bed biological filtration, in which water is passed through a fluidised bed of proprietary plastic media — K1, K1 Micro, and K+ Media — that provides surface area for the colonisation of beneficial bacteria which convert toxic ammonia and nitrite into less harmful nitrate. This biological stage is integrated with UV clarification (evoUV, NexusTi), mechanical polishing (Tempest), and pumping (Varipump) sub-systems across multiple product families. The portfolio is organised under sub-brands including Nexus, EazyPod, PURE, evoUV, and Varipump, and the company has continued to extend the range with products such as the NexusTi Titanium UV, EazyPod Automatic, and Tempest Polisher.

Evolution Aqua operates a hybrid go-to-market model combining a global network of authorised dealers (supported by an online dealer-locator tool) with direct-to-consumer e-commerce. In March 2022 the company received a £12 million growth-capital investment from BGF, with the stated objective of accelerating international expansion into commercial swimming pool and aquaculture markets. The business has since been organised under the Evolution Aqua Group structure, with additional institutional oversight added to the board as part of the investment.
