Salt mix containers are heavy and naturally more prone to minor cosmetic damage during transit. While we take great care to inspect and securely pack each order, some scuffing, denting, or surface wear may occur due to carrier handling. This type of damage is considered normal and does not affect the integrity or performance of the product. Please note that shipping insurance does not cover cosmetic damage to packaging.

Mixing Tips for Best Results:

Use clean RO/DI water with a TDS <10 (0 preferred) and mix at 70–75°F. Slowly add RPM to water to prevent oversaturation and precipitation. Mix with a pump and air stone for at least 2 hours before use, and match the temperature to your aquarium before performing a water change.


Important:

Do not mix dry salt directly in systems containing livestock. Store sealed in a cool, dry place to prevent moisture absorption.


Fritz RPM is your go-to professional salt mix for clean mixing, reliable parameters, and thriving reef ecosystems.
