Using RO/DI water is essential to maintaining a healthy aquarium. City and well water are inherently full of contaminants that have an undesirable effect on the aquarium. An RO/DI system will provide the pure water necessary for the long term success of your tank.

Benefits include:
• Contaminant free water
• A healthier reef
• Algae outbreak defense
• Faster easier water changes
• Zero trips to the store for water
