Part A Calcium

Our Coral Essentials, Part A Calcium is a concentrated source of liquid calcium, 200,000 ppm (mg/L). Calcium is an essential component in the formation of calcium carbonate skeletons, i.e. coral growth. The calcium levels in marine tanks need to be checked regularly to determine the take up in your system. How much calcium is being used can be calculated by testing at regular intervals to see how much the calcium level drops during the set interval. Then it is simple to calculate dosing requirements to suit the depletion rate. After you have determined this, a regular check of the calcium levels should be made. Your tank will change over time as coral grows, new pieces are added as well as invertebrates that also take up calcium. We have found ideal calcium levels to be at about 430-470ppm for most aquariums. Levels of 470+ ppm are desirable if you want to maintain high levels of growth in a SPS and hard coral dominant system.

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."
