    Parameters:

    • Salinity: 35 ppt (1.0264 sg)
    • Calcium: 400-450 ppm
    • Magnesium: 1300-1400 ppm
    • Alkalinity: 8.0-9.0 dKH

    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

    MIXING DIRECTIONS
    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.

    DO NOT MIX DRY SALT DIRECTLY INTO SYSTEMS WITH LIVESTOCK PRESENT!

    CAUTION: Keep out of reach of children. Not for human consumption. Generates slight heat when added to water; avoid handling with wet hands. Contact with dry powder may cause skin and/or eye irritation. In case of contact, flush eyes with cool water and seek immediate medical attention.

    Storage: Store in a cool, dry place. Keep product tightly sealed.

ONE At A Time now
Color: Aqua, Size: 2 Bowls
Thankful I bought two sets for this family of 4. Quite inconvenient to be able to make 2 people their ice cream while 2 others wait (or change their mind while waiting) Makes no sense why this set comes with ONE CHURN. Recipe booklet was minimal I got more from YouTube. Lids should come with the kit not separate. It was exciting to make yet disappointing we had to take turns and couldn't work together all at once. Ice cream was good, soft serve preferred.

Small Investment with Great Results
Color: Aqua, Size: 2 Bowls, Color: Aqua, Size: 2 Bowls
I'm just getting into making ice cream at home and after doing weeks of exhaustive research, including probably 100 hours of YouTube videos (I know, I have a problem, but the research is for me a big part of the fun), I was ready to set my budget at between $200 and $400 for a compressor ice cream machine. Then I ran across this Dash My Cup Set. I returned to YouTube and after just a few videos I decided that for a small fraction of my initial budget I could "get my feet wet" with the My Cup. Another deciding factor was that the Freezer Mugs were small enough to not sacrifice too much of my freezer space. I've made several batches of ice cream using both the included recipes and some I have found online and I must say, the results have been fabulous. Sure the finished ice cream right out of the machine is a soft serve consistency but after a couple of hours in the freezer you will have ice cream firm enough to form excellent scoops. Just be sure to follow good recipes otherwise you may end up with ice cream hard as a rock. So learning a bit about the science of ice cream is critical for good results. Although the portion size is small, it's actually bigger than I expected. I'm an ice cream lover and sure, polishing off the entire batch in one sitting is no problem but, I am definitely satisfied with the amount. And if you opt for the Set with the extra mug, you'll always have a mug ready for your next batch. Definitely the way to go in my opinion. The My Mug is very well made (as are most of the Dash products of which I have an Egg Cooker and a Waffle Iron) and the motor will turn the dasher through the thickest of recipes. If you overload with mix-ins it might run into difficulties but otherwise you're good to go. Will the My Mug be the "end game" ice cream machine? Probably not. But for a small investment I can experiment with different recipes and see where this new found hobby takes me. And even if I do get a larger, fancier and more expensive machine in the future, I will probably keep the My Mug anyway to test out new flavors. This way I can see what I like without wasting too many ingredients.

Not bad for an inexpensive ice cream maker
Color: Aqua, Size: 2 Bowls
For something this cheap, it’s definitely not that bad. The directions are easy to follow but I went and put the ice cream in the freezer for at least 30 mins more to cool the ice cream to the perfect consistency and it turned out great! After I made vanilla ice cream from the recipe in the book, I started concocting my own recipes and everything has turned out yummy!

Better than my $100 coffee maker!
Color: Black, Style: coffeemaker
Bought this to replace a very expensive coffee maker that broke after a year and a half. Works excellent! Freed up so much counter space. Saw complaints about the hot plate peeling so I always make sure the bottom of the coffee pot is dry and have had no issues. No leakage as long as the basket is in correctly. Love this simple yet very functional coffee maker.

Good buy
Color: Black, Style: coffeemaker
I have used another brand for more than two decades but the style and options have changed too much. So I gave this B+D a try. It works great! Simple to use, clean and operate. Brews coffee perfectly. Seems dependable and shuts off when it's supposed to do so. For the price range, you cannot go wrong.
