The importance of using Reverse Osmosis (RO) water for use in an aquarium cannot be overemphasized and so D-D has a full range of high quality Reverse Osmosis Units for all applications.
Reverse osmosis water is essentially free from chlorine, nitrates, phosphates and heavy metals and is an ideal base for making up salt solutions or for freshwater aquariums or replacement of evaporated loss.
Tap water is generally full of these pollutants and the effect on your aquarium can be quite severe depending on how bad the water is in your particular area, fueling algae and diatom blooms which must be then maintained by chemical methods.
3 Stage System
The three stages consist of:
1 - A 10" 5 micron pre-filter to remove sediments and particles from the mains water to protect the membrane from clogging and extend it's life. This is housed in a clear membrane to allow you to monitor the colour and life of the disposable element. We recommend that this low cost filter element is changed at a maximum interval of 6 months.
2 - A 10" 10 micron block carbon filter. This carbon filter is designed to remove the chlorine from the water. In the UK the chlorine levels are generally not high however we still recommend that you change this element every 6 months.
3 - The RO Membrane and housing. This stage holds the membrane itself. All D-D membranes are high quality thin film membranes.
