Understanding RO/DI Systems

What is an RO/DI System?

An RO/DI system, which stands for Reverse Osmosis and Deionization, is an essential tool for any reef tank enthusiast. These systems use a multi-stage filtration process to remove impurities and dissolved solids from water, creating the perfect conditions for marine life.
The process involves several filtration stages, including sediment filters, carbon filters, and a reverse osmosis membrane, followed by a deionization stage. This ensures that the water is free from harmful substances like chlorine, chloramines, and heavy metals.

Why is Purity Important?

For reef tanks, water purity is not just a preferenceโ€”it's a necessity. Corals and marine invertebrates are highly sensitive to water quality, and contaminants can lead to stress, disease, or even death.
Using a high-quality RO/DI system like those from Bulk Reef Supply or Aquatic Life ensures that your tank water mimics the natural ocean environment. This promotes coral health and growth, providing a stable ecosystem for your marine life.

Key Components of RO/DI Systems

Most RO/DI systems consist of several key components: a sediment filter, carbon block filter, RO membrane, and DI resin. Each component plays a vital role in filtering out specific contaminants.
For example, the sediment filter captures large particles, while the carbon filter removes chlorine and organic compounds. The reverse osmosis membrane targets dissolved solids. Finally, the deionization resin polishes the water, removing remaining ions.
