Reverse Osmosis

Reverse osmosis aquarium water filters attach to a tap water system in your home. The R/O filter removes most harmful metals, toxins, minerals, and chemicals invisible to the naked eye. Not only is the water that a R/O system produces perfect for drinking water, but also as a basis for the atmosphere your fish or reef will live in.

Reverse osmosis water used in a freshwater environment can be beneficial, but there are downsides. The water that a R/O system produces is almost truly pure. This means that there are no trace elements, salts, etc. These trace amounts of minerals and salts are needed for healthy fish and will need to be added to the water before use.

Reverse osmosis water in a salt or reef environment carries the same penalties as above, but the fix is much simpler. When you do your normal water changes, you are adding trace elements into the R/O water when you mix the salt. Doing normal, scheduled water changes your aquarium will continually replenish the trace elements that your inhabitants leach out. In a reef environment, adding the trace elements back into the water, especially calcium, iodine, strontium, molybdenum and other required elements are a must.

We have a huge range of reverse osmosis aquarium filters available online. If you don't see the product you require or are simply looking for some expert advice, please call our aquatic team on 01566 771878.

D-D Pen Type TDS meter
D-D Pen Type TDS meter
D-D Pen Type TDS meter Measures the total dissolved solids (TDS) in a solution. TDS is directly related to quality of water i.e. the lower the TDS figure, the more pure the water. When using RO water it is recommended to always test with a TDS meter to ensure the purity. By monitoring the RO - reverse osmosis water, you can decide when the RO filters need changing. Reverse osmosis purified water...

D-D Inline TDS meter
D-D Inline TDS meter
D-D Inline TDS meter Since dissolved ionized solids like salts and minerals contribute to the conductivity of a solution, a TDS meter measures the conductivity of the solution which is then converted to a TDS reading. TDS is directly related to quality of water i.e., the lower a TDS figure, the more pure the water. As an example, reverse osmosis purified water will have a TDS between 0 and 10, whereas...
