Reef Advantage Magnesium is a powerful (80,000 ppm) specially formulated mix of magnesium, chloride, and sulfate salts aimed at replenishing low magnesium levels while keeping the ionic ratios similar to those in natural seawater. This product is free from ammonia.


KEY FEATURES:

  • Highly concentrated, blended, and ionically balanced source of magnesium
  • Absolutely NO Ammonia
  • Crucial for preventing ionic imbalances

DIRECTIONS:
Beginner
Administer 5g (1 level teaspoon) for every 80L (20 gallons) twice weekly. Mix in a minimum of 250mL (1 cup) of freshwater. For accurate measurements, utilize the Seachem Digital Spoon Scale.

Advanced
Measure the magnesium level, then continue the dosage regimen above until achieving a magnesium level of 1,200-1,350 mg/L. Each 5 g/80 L will increase magnesium by approximately 5 mg/L. You may adjust the amount or frequency, but do not surpass 25 g/80 L in a single day. After reaching target levels, use as needed to keep magnesium stable.

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.

Love these.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I have them in black and white. I use them everyday in all shoes. These are very versatile and a great quality material. They take a looong time to wear and they stay in place. Very washable and good material. They are not too thick and they do not shrink. I do air dry mine. They do not hold smells even in the summer heat.
