FAQ:

Q: What do you need to know about the Rodi system?

A: RODI Systems are a basic law when it comes to saltwater tanks. Any saltwater aquarium should be using a Reverse Osmosis Deionized (RODI) unit. RODI water is extremely clean and ensures you will not be introducing bad things in your aquarium such as silicates, heavy metals, chorine, nitrates, and phosphates.

Q: Why do you need a Rodi water tank?

A: Phosphates and nitrates control are the biggest reasons to invest in a RODI System. Without an RODI System, you are essentially adding algae food by introducing phosphates and nitrates into your aquarium every time you change your water or top off your tank. There are also other nasties that could be in your city’s water system.

Q: Which is the best Rodi system for reefers?

A: The Kleanwater RODI is a very well priced RODI unit that can fulfill the needs of most reefers. It is a 4 stage RODI unit equipped with a pressure gauge and a TDS meter, which ensures you will always have 0 TDS water. This is a very well priced unit, but it is missing a flush valve that would extend the life of the RO membrane.
