DUO is very easy to use: it consists of only two components, which are usually dosed in the same amount. DUO does not need to be diluted or dissolved before use.

The composition of DUO prevents ionic shift (at 1:1 dosage). The pH value is raised by DUO, which accelerates the growth of hard corals.

The pH value is raised by DUO, which accelerates the growth of hard corals. By the use of DUO the use of CO2 scrubber to stabilize the PH can often become obsolete. This leads to lower operating costs.

In addition to the “main parameters” of calcium and alkalinity, DUO doses many other substances: strontium, boron, iodine, fluoride, bromide, sulfate, potassium, rubidium,selenium and magnesium. As a result, these important water parameters are adjusted to the coral’s consumption.

DUO dispenses with an organic content: this allows the product to be diluted as required, and the dosing of DUO does not deprive the aquarium water of any oxygen.

In our laboratory, all raw materials and products undergo a strict quality control (using ICP-MS and other methods). This enables us to guarantee the consistently high quality of our products.
