Aquaforest Magnesium Dry
Aquaforest Magnesium Dry is a dry magnesium conditioner for reef aquariums, used to maintain proper magnesium levels and support coral development. It suits marine hobbyists who dose their own additives and want steadier calcium and alkalinity in SPS, LPS and soft coral systems, as well as tanks with clams.
Key Benefits
- Maintains magnesium at proper levels in reef aquaria, which supports coral development.
- Helps stabilise calcium and alkalinity. Magnesium lets both become supersaturated while keeping them steady and balanced.
- Magnesium is an essential part of coral development and overall water chemistry, so it is a core parameter to keep on target.
- Dry magnesium additives are very cost-effective. Mixed into a solution, they can work just as well as liquid additives, or better.
- Can be mixed with Calcium Dry into one solution, so calcium and magnesium can be maintained with a single dosing pump.
Why Magnesium Matters
Magnesium has several roles in a reef tank. Its best-known one is letting calcium and alkalinity stay supersaturated without losing balance. Low magnesium may leave you unable to maintain proper calcium levels, and it may also lead to a pH that is too low. The recommended magnesium level in reef aquaria is 1180-1460 mg/l (ppm).
How to Use
- Test your water first to check current parameters before adding any magnesium solution.
- Dissolve 10 g of Aquaforest Magnesium Dry in 1000 ml of RODI water to make the solution.
- Set the dose from your water test results and your corals' daily consumption.
- If you are adding a calcium solution, add it slowly to a high-flow area of the tank to help reduce precipitation.
- To maintain ionic balance, KH Buffer and Reef Mineral Salt should also be applied.
- Magnesium and Calcium, or Reef Mineral Salt, can be combined into one solution.
Dosage
- Solution strength: 10 g dissolved in 1000 ml RODI water.
- 100 ml of magnesium solution in 100 l of water raises the magnesium level by 1,2 mg/l (ppm).
- Do not raise magnesium by more than 50 ppm per day.
- Always base the actual dose on your test results and your corals' daily consumption.
Suitable For
- SPS corals
- LPS corals
- Soft corals
- Clams
Compatibility
Aquaforest Magnesium Dry can be mixed with Calcium Dry to create one solution that maintains proper calcium and magnesium levels with a single dosing pump. It can also be combined with Reef Mineral Salt. KH Buffer and Reef Mineral Salt should be used alongside it to keep the water ionically balanced.

Frequently Asked Questions
How do I make up the magnesium solution?
Dissolve 10 g of Aquaforest Magnesium Dry in 1000 ml of RODI water.
What magnesium level should I aim for in my reef tank?
The recommended range is 1180-1460 mg/l (ppm). Test your water before dosing so you know where you are starting from.
How much will the solution raise my magnesium level?
100 ml of the solution in 100 l of water raises magnesium by 1,2 mg/l (ppm). Do not raise it by more than 50 ppm in a day.
Can I dose it together with Calcium Dry?
Yes. Magnesium Dry can be mixed with Calcium Dry into one solution, so a single dosing pump can maintain both calcium and magnesium. Magnesium and Calcium, or Reef Mineral Salt, can be combined into one solution.
What can happen if my magnesium is too low?
Low magnesium may make it hard to maintain proper calcium levels and may result in a pH that is too low. Regular testing helps you catch this early.
Which animals is it suitable for?
It can be used with SPS corals, LPS corals, soft corals and clams.
