Refill Cartridges / Membranes

RO units are a fantastic piece of kit which effectively removes contaminants from water in order to make it pure and safe to be used in an aquarium.

Maintaining the semi-permeable membrane within your RO unit is essential to efficient running as well as the other spares you see below.

While RO units work efficiently to purify the water, some people like to use extra pieces of kit such as the D-D 300ml Deionising Pot with Resin to assist in the removal of any unwanted compounds.

At Swell we have a selection of refill cartridges and membranes to work alongside the RO units to help to purify the water, all at competitive prices.
