The automatic source of nutrients for magnesium
Our solution for automated, controlled and exact dispensing of magnesium (Mg) in seawater aquariums without the need to purchase an expensive, failure-prone electro-mechanical dispensing pump.
This is a special challenge for substances which may be dispensed in large quantities permanently. However, with DRAK Sealutions Origin, you can achieve maximum precision.
The innovative Aquafim® material in a mesh bag ensures even dispensing of magnesium over a guaranteed period of 1 month. The mesh bag is then simply replaced with a new one.
Discharge time: 1 month
Discharge amount per mesh bag: 15 mg magnesium (absolute) per day
If you require more, please simply use the relevant number of mesh bags.
Position in filter/sump tanks or at another place with a good flow of water.
Briefly rinse under running water before initial use.
We exclusively use salt in purest quality and higher.
Does not contain chelating agents!
The aimed (natural) magnesium content of salt water is approx. 1,350 (1,200 - 1,400) mg/l.
Magnesium is necessary for the ion balance, and binds the silicic acid within the water.
In particular, coralline algae and sea fans have a high magnesium requirement and consumption, but also hard corals, sponges, sea urchins, crabs, mussels and snails require smaller amounts of magnesium for building their skeletons.
Possible consequences of a low magnesium content
- Stone corals and coralline red algae suffer from disturbances of growth
- Echinoderms show an insufficient skeleton and crayfish moulting problems
The difference between the total hardness (Ca + Mg) and the calcium content displays the current magnesium content.
Thereby 1° dH total hardness equals 0.179 mmol/l alkaline earth ions or converted 4.35 mg/l Mg or 7.17 mg/l Ca.
