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.

Handy Compact Trimmer
I really like how this trimmer has two functions in one, it makes things super convenient. It’s small and easy to hold, so I can use it on different areas without feeling awkward. I tried it on both legs and underarms, and it gave a smooth finish without irritation. The design makes it easy to switch between trimming and shaving, which is a nice touch. I also appreciate that it’s waterproof, so I can just rinse it clean after using it. Overall, it feels like a simple and practical tool to keep around for quick grooming.

efficiently remove body hair
It is excellent bikini trimmer to trim overgrown hair. Works great and super easy to use. It's easy to handle, charges quickly, and trims without irritation. I like the 2 in 1 dual side design. The round head hair remover works very efficient and after removal of arm hair, I don't feel any pain. And the residue hair could be released from the device easily. Perfect for travel or quick touch-ups at home. Love the cute design and color. It is affordable bikini trimmer that gets the job done without irritation or nicks.

Functional
I used to get cuts when using regular razors but ever since I switched to this electric razor, I no longer have to worry about getting hurt. The blade is extremely sharp yet gentle and provides a smooth shave on my face, legs, underarms and other areas without any pain. The waterproof feature makes cleaning easy. I can simply rinse it under the tap. The rechargeable design is also very convenient. It's small and portable easy to take on business trips and travels! The shaver glides smoothly on underarms and the detailer head gives perfect shaping for bikini lines. Fully waterproof for shower use and the self cleaning blades rinse effortlessly.

A little drying but amazing
First thing to note is this is a soap, not a cleansing bar, so it WILL dry you out if you use it too much. but the smell is irresistible, and it definitely conditions your skin well. I wouldn't say it has a slimy texture like advertised, but it is still really pleasant and the foam is so rich with herbal aromas. Definitely not a good value for the money, but I consider this like a luxury splurge soap bar for when I want to treat my senses rather than a daily driver cleanser bar.
