Reef Advantage Magnesium 600 g Seachem – magnesium supplement for reef aquarium

Magnesium is a major element in seawater and plays a key role in the chemical stability of reef aquariums. It contributes to the overall ionic balance and helps maintain stable parameters, including calcium and alkalinity.

Reef Advantage Magnesium is a concentrated, ionically balanced blend of magnesium salts, chloride, and sulfate. Its formulation effectively corrects magnesium deficiencies with minimal impact on natural ionic ratios. This product does not contain ammonia, a contaminant commonly found in liquid magnesium supplements.

Too low magnesium levels, particularly below 800 mg/L, can lead to a drop in pH and make it difficult to maintain stable parameters. Common causes of deficiency include the use of kalkwasser, overdosing of carbonate additives, or insufficient magnesium content in the salt used.

Main Features

Parameter Targets

The recommended magnesium level in a reef aquarium is between 1,200 and 1,350 mg/L.

Instructions for Use

Beginner Level

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

Dissolve the dose in at least 250 ml of freshwater before adding to the aquarium.

For precise dosing, the use of a digital spoon scale is recommended.

Advanced Level

Measure the magnesium level, then follow the addition pattern above until reaching a concentration between 1,200 and 1,350 mg/L.

Each 5 g dose for 80 L increases the magnesium by approximately 5 mg/L.

The amount or frequency can be adjusted as needed, without exceeding 25 g for 80 L per day.

Subsequently, use as needed to maintain the magnesium level.

Expert Level

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

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

Example: to increase magnesium by 10 mg/L in a 200 L aquarium, add 25 g in the top-up water.

Important Considerations

Regularly test magnesium with a suitable test to ensure parameter stability.

Significant adjustments should be made gradually to avoid drift.

An excess of magnesium can accentuate the loss of carbonate alkalinity.

Do not mix directly with a carbonate supplement.

It is recommended to add magnesium and carbonate supplements every other day or at least 30 minutes apart.

Slight clumping of the product may occur without affecting its effectiveness; the clumps disintegrate easily.
