Reverse Osmosis filters work using incredibly fine membranes to filter tap water, leaving amazingly clear, soft, salt-free water. This pure water is a great basis for a healthy aquarium. Reverse osmosis systems can even remove most bacteria and viruses.
At 123 Aquatics we supply high quality water purification systems from JBL and D-D, which are ideal for freshwater and marine aquarium set ups. They remove all manner of heavy metals and pollutants that can be found in tap water. By removing these, your fish tank will be clearer and your fish healthier.
