Randy's 2 Recipe Calculator

Randy's Recipe has often been a favourite of reefers all around the world. Without the input Randy Holmes-Farley has had in the marine reef aquarium industry and hobby I doubt it would ever have been so popular now. A lot of reefers are very familiar with Randy's recipe and currently dose their primary elements using Randy's mix. We thought it very helpful for our Coral Essentials users that we provide a simple instruction set to convert our products to the equivalent Randy's recipe. That way when they purchase our products you can easily continue to use your Randy's dosage rates.

Calcium @ 18,500ppm
Carbonate (Alkalinity) @ 47,500ppm (950 meq/L of alkalinity or 2,660 dKH)
Magnesium @ 47,000ppm

What Our Clients Are Saying

"I've been using the range of Coral Essentials products for the last couple of months. I've just started into my 3rd lot of bottles. I dose Trace Elements A, B & C along with Boron and Bromide. I manually dose their excellent concentrates, Coral Power Gro and Coral Power Amino. My tank has improved dramatically after ditching a well known and expensive product that has seen my tank almost crash totally on several occasions. Coral essentials is also very reasonably priced, so much so, that I can now afford to splurge out and buy Sustainable Reefs frags that are second to none! If you want quality at an affordable price, and clearly visable results, I thoroughly recommend the products. Coral Essentials, along with Sustainable Reefs expert advise, has helped me get my tank looking just like the photos they post."
