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.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.

My dog doesn't like it
Size: 5 in, Color: Orange
My dog wasn't a fan of this at all. He was curious about it, probably because he could smell it, but he wasn't sure about chewing it. It could be because his teeth squeak against it? Or maybe it has an odd texture? I don't know But this has sat in the toy bin untouched since the day we got it

Great Chew Toy for Daily Play
Size: 6 in, Color: Blue, Size: 6 in, Color: Blue
My dog absolutely loves this toy. From the first moment he grabbed it, he wouldn’t stop playing with it. He chews on it, runs around with it, and even sleeps with it sometimes. What I like most is how durable it is — even with constant biting, pulling, and chewing, it hasn’t broken or shown any damage. The material feels strong but still safe for him to chew. The texture also seems to keep him entertained because it massages his gums while he plays. It’s lightweight, easy for him to carry, and the shape makes it fun for both chewing and tossing. This toy has become one of his favorites, and I’m really happy with the quality. I would definitely recommend it for dogs who love to chew.
