Reef ADV Magnesium 300 grams SEACHEM

Reef Advantage Magnesium 300 g Seachem – magnesium supplement for reef aquarium

Reef Advantage Magnesium is a concentrated, ionically balanced blend of magnesium salts, chloride, and sulfate, formulated to correct magnesium deficiencies while respecting the ionic ratios of natural seawater.

Main Features

Role of Magnesium in Reefs

Magnesium plays an essential role in the chemical stability of the reef aquarium. Levels that are too low, generally below 800 mg/L, can lead to a drop in pH and make it difficult to maintain correct calcium and alkalinity concentrations.

Common causes of magnesium deficiency include the use of kalkwasser, repeated overdosing of carbonate supplements, or low magnesium content in the salt used. Kalkwasser precipitates magnesium as magnesium hydroxide, while an excess of carbonates transforms it into magnesium carbonate, thus reducing its availability.

Benefits of Reef Advantage Magnesium

Reef Advantage Magnesium effectively restores magnesium levels with minimal impact on the overall ionic balance. Its dry formulation contains no ammonia, a contaminant frequently found in liquid magnesium supplements.

Usage Instructions

Beginner Level

Use 5 g per 80 L of water, twice a week.

Dissolve in at least 250 ml of freshwater before adding.

Advanced Level

Measure the magnesium level, then follow the addition schedule to reach a concentration between 1200 and 1350 mg/L.

Each dose of 5 g per 80 L increases magnesium by about 5 mg/L.

The amount or frequency can be adjusted, not exceeding 25 g per 80 L per day.

Expert Level

After determining the magnesium consumption rate, a continuous drip system can be set up.

The amount to add to the top-up water can be calculated using the following formula: g = v × m ÷ 80, where g corresponds to the grams to add, v to the volume of the aquarium in liters, and m to the desired increase in mg/L.

Important Considerations

The recommended magnesium level is between 1200 and 1350 mg/L.

Significant adjustments should be made gradually to avoid any imbalance.

Excess magnesium can increase the loss of carbonate alkalinity.

Do not mix directly with a carbonate supplement. It is recommended to space additions by at least 30 minutes.

Slight clumping of the product may occur without affecting its effectiveness. Clumps break apart easily.

Frequently Asked Questions

Use in Automatic Dosing System

Reef Advantage Magnesium can be used in automatic dosing after a precise calculation of weekly magnesium needs. The recommended solubility ranges between 1 and 2 cups of product per liter of water, depending on the usage conditions.
