Aquaforest Magnesium Dry

Aquaforest Magnesium Dry is used to maintain proper magnesium levels in reef aquaria, supporting coral development and stabilizing calcium and alkalinity.

Magnesium is an essential part of coral development and water chemistry. Magnesium has multiple roles in the reef tank, most notably its ability to let calcium and alkalinity become supersaturated and keeping them steady and balanced. Dry Magnesium additives are very cost-effective and when mixed into a solution can be just as good or better than liquid additives.

Lowered magnesium levels may cause an inability to maintain proper calcium levels and too low pH. The recommended level of magnesium in reef aquaria is 1180-1460 mg/l (ppm).

Aquaforest Magnesium Dry can be mixed with Calcium Dry to create a solution that when dosed will maintain proper calcium and magnesium levels with a single dosing pump. 

Magnesium Dry can be used with:

  • SPS corals
  • LPS Corals
  • Soft Corals
  • Clams 

Instructions:

Dissolve 10 g in 1000 ml RODI water. Dosage should be determined by your water test results and corals daily consumption.

Before applying Magnesium solution into the water, it is recommended to run a water test to check current water parameters.

100 ml of Magnesium solution in 100 l of water raises Magnesium level by 1,2 mg/l (ppm). It is not recommended to raise Magnesium levels by more than 50 ppm daily. 

It is highly recommended to add calcium solution slowly to a high-flow area of the tank to help reduce any precipitation.

In order to maintain ionic balance KH Buffer and Reef Mineral Salt should also be applied. Magnesium and Calcium or Reef Mineral Salt can be combined together into one solution.  

Contains: Magnesium chloride

My favorite new mineral sunscreen!
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
This is my favorite new mineral sunscreen! I've been searching for years for a product that is easy to apply, not messy, and doesn't show up too white. This roll-on is the perfect solution. I keep it near the front door and quickly roll the sunscreen on my hands, arms, and chest before leaving the house. The sunscreen applies so quickly and uniformly-- there are no bare spots or messy globs to rub in. Also, the roll-on keeps the sunscreen from oozing out of the tube and getting all over everything. Finally, the roll-on method also eliminates the frustration of having half-filled tubes and pumps where you can't even access the sunscreen when the tube gets low. Here's hoping this doesn't happen with the roll-on. Thank you Sun Bum for creating this wonderful product. I also love the reasonable price.

great product - it must be blended in well
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Love this stuff. The roll-on makes it easy to apply on the go. It leaves a white streak unless you blend it in. I don't mind the white streak - at least I know I applied the product.
