Marine

Purity on Tap was the first company to launch a nationally recognised range of UK designed and produced aquatic RO systems in 1991.  We continue to offer premium quality systems at realistic prices in the belief Aquarists deserve systems designed to last many years.

With our long-standing experience and knowledge of the reverse osmosis industry, we have insured our pre-filtration is correctly matched to the production of the membrane and we find our twin pre-filter systems can easily outperform triple pre-filter units. We feel our SP and Ultro series is a real step forward for efficiency and value.

This range is ideal for Discus, Marine and water softening applications.
