Aquarium Reverse Osmosis Deionization Filter Info
One of the pieces of equipment you might be interested in for your aquarium is a Reverse Osmosis / Deionization water filter. These are sometimes simply called RO/DI units. If you keep an aquarium that runs high output flourescent or metal halide lighting, like for a reef tank or a freshwater planted tank, you probably should know about these water purification devices.
Running high output lights can really spell trouble in an unbalanced tank loaded with nitrates, phosphates and other dissolved organics that can lead to algae blooms. Starting with good source water out of the tap for water top-offs, water changes, and tank fillings can become a crucial component for your aquarium. That is where the Reverse Osmosis and/or Deionization unit comes to the rescue. These units are used to remove the vast majority (like 95 – 99%) of the impurities found in tap water.

I just wanted to add on that there are alot of chemicals in tap water that aren’t natural in the ocean. We want to try and mimic what is out in the real ocean where these plants and animals come from. You also will have high silicates as well, with tap water which is bad. Also, if you do run an RO unit, i like the units with the dual TDS (Total Dissolved Solids) meter. This is good indication of when its time to replace your filters.
