Product Information
Seachem Reef Advantage Magnesium is a concentrated (80,000 ppm) optimised blend of magnesium, chloride, and sulphate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water.
If depleted these levels can affect pH and calcium levels. So, it's important to regulate the amount of magnesium. Seachem's Reef Advantage Magnesium will ensure that corals and other organisms have just the right amount for healthy balance and growth. Unlike many other magnesium supplements, it doesn't contain ammonia. So you can be confident of both great water quality and fish health.
Key Features:
- Contains magnesium, chloride, and sulphate salts
- Promotes healthy balance and growth of corals
- No ammonia
Dosage: Use 5g (one level teaspoon) per 80 litres / 17.6 gallons, twice a week. Dissolve in at least 250ml of freshwater.

I've used this product before and liked it, but this particular pack was damp, so the chrystals had clumped together into a lump.
