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.

Worth the money!
Size: 50mm/2inch, Color: Black, Number of Items: 2
This kit is great. I bought this because I know that the seller paired the cutting tool to be the perfect size and it was! Not just that, but the hole cutter was well done and cut thru the 3 layers - laminate, plywood and particle board with ease. The only thing that I would do different, is go to 3" next time. 2" was very tight when running the 2 @ 120 volt cord ends through the cap.

I wasn't sure how to fill this space between my kitchen cabinets, and I think these shelves turned out looking great and fit the space nicely. They were easy to install, good quality, and could handle a decent amount of weight.
