Tropic Marin Bio Magnesium 450g

Tropic Marin Bio-Magnesium

Biologically ideal Magnesium Supplement for Reef Aquariums.

A sufficient supply of magnesium is as essential for the growth and well being of reef building coralline algae as calcium. It is one of the major constituents of seawater and is directly involved in algae photosynthesis, i.e. the conversion of carbon dioxide (CO2) and light into organic compounds. The addition of plain magnesium salt, however, is not sufficient and interferes with the ionic balance of the tank water.

Tropic Marin Bio-Magnesium creates a natural environment in the aquarium and delivers Magnesium in a natural biologically available ionically balanced form.

Salifert Liquid Magnesium 250ml

Magnesium is present in natural sea water in fairly high concentrations (1350 - 1500 mg/l). Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Without photosynthesis algae and hence the corals, which we have in our aquariums, would not survive. Magnesium also has another important function in that it allows maintaining the correct combination of calcium concentration and alkalinity or carbonate hardness possible. Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth. Magnesium is depleted by algae growth and also by the use of excessive kalkwasser or by going far beyond natural calcium, alkalinity and pH values.

This supplement is highly concentrated. Each liter contains approximately 25 000 mg of magnesium. To avoid an ionic imbalance, Salifert have properly balanced the magnesium with ions such as sulphate, chloride, bromide, sodium and calcium.

This supplement is intended to be used on a regular maintenance basis. If the magnesium concentration is significantly lower than 1350 mg/l we advise the use of Magnesium Powder.

Directions:

Shake well before use.
Dose 5ml per 100lts once a week.
Adjust dosage according to individual requirements using a Magnesium test kit.
Every 5ml per 10 litres will increase the magnesium concentration by approximately 12.5mg/l.
Never increase the magnesium concentration by more than 50mg/l a day.

Grotech Magnesium Pro Instant 1000g

Immediately soluble Magnesium

In the marine water aquarium, great quantities of Calcium and Magnesium are required, in order to achieve an optimum growth of corals and red calc algaes.

In case of larger deviations, the quantity should be increased over a period of numerous days via the refill water.
In case of minor quantities, please dose directly into the filter bassin at a well- floated area.

For a constant Magnesium level in the aquarium, we recommend to admix Magnesium pro in the Calcium reactor.

When using Magnesium pro instant in the aquarium, please check regularly the Calcium contents of the aquarium water.

The optimum value is at abt. 1330mg/l.

1 measuring spoon (abt. 10g) results in an increase of the Magnesium contents by abt. 11mg per 100 liter aquarium water, without shifting of the ion balance.

Magnesium Pro 1000g

Additive for the Calcium reactor for the increase of the Magnesium contents.

In the marine water aquarium, a great quantity of Calcium and Magnesium is required in order to achieve an optimum growth of corals and red calc algaes.

By the normally used materials in the Calcium reactor, the Calcium content will be more increased than the Magnesium content.

By admixing of up to 10% Magnesium pro into the used material, there will continuously befed Magnesium and the Magnesium contents in the aquarium is stabilized.
