The Pro Products RU15N is a specialty powdered solution designed to neutralize and raise the pH of acidic water in neutralizer tanks that use calcite or Corosex media. It helps dissolve hardened mineral deposits, free stuck media beds, and restore proper flow and neutralization performance in acid neutralizer systems. The RU15N is packaged in a 1.5 lb container, making it ideal for periodic maintenance of residential whole-house acid neutralizer tanks.

For most residential acid neutralizer systems, Pro Products recommends using RU15N every 6 to 12 months, depending on your water's acidity and usage levels. Homes with highly acidic water (low pH below 6.0) or high water consumption may benefit from more frequent applications. Regular use of RU15N helps prevent media compaction (cementing), maintains consistent pH correction, and extends the life of your calcite or Corosex media bed.

To apply the RU15N, first bypass your neutralizer tank and relieve system pressure. Remove the control valve or access port, then pour the recommended dosage (typically the full 1.5 lb container for standard residential tanks) directly into the media bed. Allow the product to sit for 4–8 hours to break down cemented media and neutralize buildup. Afterward, backwash the tank thoroughly to flush out residue before returning the system to service. Always follow the full instructions on the RU15N label for your specific tank size.

Yes, the RU15N is specifically formulated to be safe and effective for use with calcite and Corosex neutralizing media. Unlike harsh chemical cleaners, it works by gently breaking down hardened mineral deposits and cemented layers without damaging the media itself. This allows the media bed to loosen up, resume proper contact with water, and continue raising pH effectively. The RU15N is not intended for use in water softeners or iron filter systems.

In most cases, yes. After a single application of RU15N followed by a proper backwash cycle, customers typically notice restored water flow, reduced pressure drop across the neutralizer tank, and improved pH balance in their household water. If your media bed is severely compacted or nearing the end of its service life (typically 4–7 years for calcite), a second treatment or full media replacement may be required. Routine use of the RU15N every 6–12 months helps avoid severe buildup and keeps your neutralizer operating at peak performance.
