Calcium, magnesium, KH & trace elements




Product description

Through the growth of organisms and other processes in the aquarium, minerals are consumed and must therefore be supplemented regularly. These include, in particular, the necessary elements calcium, magnesium and strontium, as well as alkalinity for the growth of calcium carbonate skeletons in stony corals, lime red algae and other reef organisms. Tropic Marin® All-For-Reef contains all of these components in a highly concentrated form. In addition, all essential trace elements are also included: Iodine, bromine and fluorine for the growth and strengthening of skeletons in gorgonian corals, sponges and crabs; selenium for eliminating free radicals, and iron, manganese, zinc, copper, nickel, chromium, cobalt, molybdenum and vanadium for the development of important enzyme complexes.


With these components and balanced in its concentration ratio, Tropic Marin® All-For-Reef creates the best care conditions with just one solution. There are no additional compounds (e.g. sodium chloride) that alter the salinity or ion balance.

Tropic Marin® All-For-Reef Powder is an ultra-concentrated mineral blend, with which an easy-to-use, highly concentrated all-round solution for supplying all key minerals and trace elements in newly established and averaged reef aquariums is available after being dissolved in reverse osmosis water.



  • Complete mineral supply with only one solution

  • All essential trace elements are already included (all elements of the Tropic Marin® K+ and A- Elements)

  • No formation of by-products (e.g. sodium chloride); the salinity and the ion balance are not changed

  • No formation of excess carbon dioxide

  • Suitable for aquarium stocking with soft corals, LPS, SPS, azooxanthellate filter and/or crustaceans

  • Easy to use - suitable for both manual dosage and for dosing pumps



organic calcium salts, salts of magnesium, strontium and trace elements (barium, boron, bromine, chrome,iron, fluorine, iodine, cobalt, copper, lithium, manganese, molybdenum, nickel, selenium, strontium, vanadium and zinc)


Application & Dosage

Before starting use of Tropic Marin® All-For-Reef as a supplement for your aquarium, it is recommended to adjust your systems calcium, alkalinity and magnesium to your desired values. We recommend using Tropic Marin® Original Balling - Part A (calcium chloride) for the calcium, Tropic Marin® Original Balling - Part B (sodium bicarbonate) for the alkalinity and Tropic Marin® Bio-Magnesium

Preparation of the solution from powder:

The 800 g can of All-For-Reef Powder makes 5 litres of dosing solution, the 1600 g can is enough for 10 litres of dosing solution.

To prepare the liquid mineral mixture, dissolve 6 level scoops (approx. 160 g) of Tropic Marin® All-For-Reef Powder in approx. 900 ml of reverse osmosis water, resulting in a total of 1 l of dosing solution.



Start with a daily dose of 5 ml of Tropic Marin® All-For-Reef per 100 liters (26 US-gal) of aquarium system volume. Increase the daily dosage weekly by 2.5 ml per 100 l (26 US-gal) aquarium volume until you reach constant alkalinity and calcium concentrations.

Once the dosage is established, and the system parameters are stable, measuring either calcium or alkalinity, on a regular basis will monitor your systems changes and needed dosage adjustments. The corresponding parameter only needs to be monitored periodically. We recommend using Calcium as the dosage regulator, as conventional test kits are more sensitive (or accurate) in measuring changes in the calcium concentration than changes of the alkalinity from Tropic Marin® All-For-Reef.


Maximum Dosage:

We recommend not to exceed a daily dose of 25 ml of Tropic Marin® All-For-Reef per 100 liters (26 US-gal) of aquarium system volume


In some cases, calcium and alkalinity may be consumed in different ratios than from the coral’s needs alone. If this occurs, and parameters become unbalanced, use the chart to make the proper corrections.

Other product recommendations

For further colour intensification of the corals, improved polyp appearance and growth, we recommend Tropic Marin® Reef Actif.


The very accurate, easy-to-perform Tropic Marin® water tests KH/Alkalinity-Test Professional or Calcium/Magnesium-Test Professional are suitable for checking the water quality and essential parameters.
