Salinity: 35 ppt (1.0264 sg)

Calcium: 400-450 ppm

Magnesium: 1300-1400 ppm

Alkalinity: 8.0-9.0 dKH

Strontium: 9 ppm

Potassium: 400 ppm

RPM parameters reflect Fritz Aquatics’ QC pass ranges, the median is targeted. Be aware source water can greatly affect parameters especially alkalinity. QC is conducted using RO/DI at a neutral pH and a TDS of 0.

RPM is manufactured in our own facility in small batches to ensure complete quality control, rather than outsourced to generic chemical blenders with uncertain quality. Our salt blending equipment is devoted solely to the production of aquatic products, preventing contamination issues. Fritz’s unique production process promotes a uniform particle size minimizing stratification of the salts. Each batch is assigned a lot number and tested by in-house quality control to ensure its chemical quality and purity before it is shipped.

RPM is used by public aquariums, zoos, research institutions, destination retail locations, adventure parks and hobbyists worldwide.

Directions & Dosage


For best results, it is important to follow proper mixing instructions when using salt with elevated parameters like Fritz Aquatics Reef Pro Mix. See below for best practices when using RPM.

When mixing Fritz Reef Pro Mix, it is best to use RO/DI water quality checked by a TDS meter (TDS should be less than 10 ppm, 0 is preferred). Fill a clean mixing container (dedicated to saltwater mixing only) with desired amount of water to be prepared. For best results, use water between 70°-75°F (21°-24°C) when mixing RPM. Slowly add desired amount of RPM to the water to avoid an increase in temperature and precipitation. This helps to prevent precipitation of calcium, alkalinity and other elements. It is recommended to use a mixing pump and an airstone when mixing RPM. This will also help to avoid concentrated areas of material and precipitation. Using a properly calibrated refractometer, bring the water to the desired salinity. Once mixed to a clear solution, add a heater to the water to bring to the current temperature of your aquarium. It is recommended to allow two hours before performing a water change. If water does not mix clear, please contact us for further mixing tips before performing a water change.


User Reviews

This salt is a great improvement over the old salt reef mix.

I’ve had a great experience with this salt. I’ve had no problems with chemical spikes, and my levels have stayed on point during the switch. Following directions is essential; mixing by the 5-gallon bucket allows you to see when it’s clear enough to use in your tank. I drop in a heater after the salt clears, which takes about 15 minutes, and when it warms up, it’s ready for use.

Reef salt mixes easily, dissolving faster than other types of aquarium salt.

Fantastic Salt is specifically formulated to provide the ideal strength of salt concentration for a mixed reef aquarium. It mixes easily, dissolves quickly, and does not leave behind any residue or crystals to foul your aquarium equipment.

Fritz Pro is a great salt blend for a great price. I use it for my marine fish, and it dissolves completely in the aquarium. It’s a lot better than instant ocean, which can make your water cloudy.

I recently switched to Fritz Pro after reading the positive reviews.

I’ve been using Seachem Aquavitro Salinity since I got into reef keeping. I noticed the parameters were all over the place in the last few buckets and the price keeps going up every time I buy it, so I settled on trying Fritz Pro just from what I’ve been reading about them. Glad to hear good reviews from people who have actually used it!

I am very impressed with this salt! I have been using Red Sea pro

This salt has helped me to improve coral growth and coloration, as well as to maintain a more consistent salinity level in my tank.

I mix 1/2 cup of this salt per gallon of water when the water’s temperature is 77 degrees, and by the time I’m ready to use the mixture 30 minutes later, it’s ready. This salt makes my tank levels very stable, so I do less water changes now. I recommend it to anyone who wants to keep their tank levels in this range.
