New Calcium UP


Our Coral Essentials Calcium Up is concentrated Calcium Chloride granules at 94% purity, in a handy 3kg bucket.  For those marine reefers with large tanks it is an extremely cost effective way of providing your calcium dosing. You can follow our simple recipe to make up solutions at 100,000ppm to match the calcium concentration of our renowned Calcium + Trace pre-mix liquid solution, the full bucket makes up 10L at 100,000ppm.  You can also use the familiar Randy’s 1 and 2 mixes. All instructions for the above are detailed on the bucket itself.  Then simply add our Power Trace A and B for  the complete calcium dosing additive with essential trace elements. For optimum results the Calcium levels in marine tanks need to be checked regularly to determine the uptake in your system. Simply calculate dosing requirements to suit the depletion rate using our easy to use dosing calculator on 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. We have found ideal calcium levels to be at about natural sea water levels for most aquariums. Levels of 430-470ppm are desirable if you want to maintain high levels of growth in a SPS and hard coral dominant system.

The following steps use 9 products in our range to replicate the premix primary care dosing solutions you already love with more value for you. The 50ml trace element “Coral Power” blue bottles can be used for up to 50L of solution!
Step 1. Have approximately 30L of RO or RO/DI water on hand.
Step 3. Have a mixing vessel/bucket with line marked for 10L.
Pro Tip: A dedicated paint mixer on a drill is a fast and effective way to mix these up!
Step 3. Pour about 9L of RO water into the mixing bucket.
Step 4. Slowly add the entire pre measured amount of Calcium powder to the water, stirring as you go until it’s dissolved. This solution will get quite hot, it’s normal. Avoid powder contact with skin.
Step 5. Add the remaining water to the 10L mark and stir the solution again.
Step 6. Add 1ml per litre (10ml if you used all of the powder) of both Coral Power Traces A and B. Mix in the trace elements well.
