Reef Advantage Magnesium is a potent (80,000 ppm) specially formulated mix of magnesium, chloride, and sulfate salts aimed at replenishing low magnesium levels while ensuring minimal disruption to the ionic balance typical of natural seawater. This product is free from ammonia.


KEY FEATURES:

  • Highly concentrated, harmoniously blended magnesium source
  • Completely Ammonia-Free
  • Essential for maintaining ionic balance

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

Advanced
Monitor magnesium levels, then adhere to the addition schedule mentioned above until magnesium reaches between 1,200-1,350 mg/L. Each 5 g per 80 L will increase magnesium by roughly 5 mg/L. You may adjust the amount or frequency, but do not exceed 25 g per 80 L daily. After reaching the desired level, use as necessary to sustain magnesium levels.

Nice, lightweight blanket for cool rooms. Probably a bit light for a COLD room.
Color: Dark Grey, Size: Queen
This is a nice soft lightweight blanket. The only problem I have is they don't come in a "standard" mattress size, so you order something that may (does in my case) touch the floor. I'd have said they drag the floor, but that only happens when you move the bed around the room with the blanket in place. An unhandy way to clean the floor, so I don't recommend it.

Summer perfect! Soft and light
Color: White, Size: Twin
I bought 3. As soon as I opened the bag there was an odor to them. They didn’t feel like made with natural products. I washed them & when they came out of the dryer they smelled good & are so soft. I will order other colors.

Impossible to keep clean
Color: White, Size: Queen, Color: White, Size: Queen
Great blanket. How TF are you supposed to keep it clean? They provide garment bag, but my zipper broke before I could even use it. I had one of these before and my ex lost the bag, so I had no idea it even came with one. These rip and get burned in the dryer. DON’T WASTE YOUR MONEY
