Product Information

API Crystal cleans and clears aquarium water, leaving you with crystal clear water. It is suitable for freshwater, saltwater and reef aquariums. These cartridges work in the API Rena NEXX filter.

API Crystal is scientifically proven to remove organic aquarium pollutants, inncluding colours, odours, heavy metals and toxic gases which cloud water and degrade water quality.

The Api Rena Nexx Crystal Size 4 has a pre-dosed cartridge for mechanical and chemical filtration. It offers optimum microfiltration with activated carbon and superior resins.

The research-grade resin-carbon blend removes compounds that carbon alone cannot remove.

Rena Crystal Cartridges also absorb unwanted odours and colours. There is a large range of Rena Spares and Rena Parts and these Crystal Cartridges should last for several weeks

Available in packs of 2 or 4.
