Ion-B Ca/Mg+ Powder Mix 1122g (makes 3L) & 2245g (makes 6L)

ION-B CA/MG+ powder mix creates a concentrated solution for increasing calcium and magnesium. It is part of the Nyos® ION-B method.

• 1,122g unit: Makes 3,000ml (101 fl. oz.) solution
• 2,245g unit: Makes 6,000ml (203 fl. oz.) solution
• Increases calcium and magnesium
• Also contains magnesium, strontium, potassium and boron for ion balancing

Instructions:

• 1,122g unit: Dissolve entire contents in 2.4 liters (82 fl. oz.) of RO water. This results in 3,000ml (101 fl. oz.) of CA/MG+ solution.
• 2,245g unit: Dissolve entire contents in 4.8 liters of RO water. This results in 6,000ml (203 fl. oz.) of CA/MG+ solution.
• Dosage should replenish daily consumption of calcium
• 1,000ml (34 fl. oz.) of ION-B CA/MG+ contain approx. 72,000 mg Ca
• Guideline for dosage: 5-10ml/day per 100 L (25 gal) of tank water
  
  

Note

Alkalinity and Calcium are consumed by corals in a ratio of about 1:7. The ION-B solutions are also in a ratio of 1:7, so dosing should be equal amounts of both solutions.

1. Calcium & Alkalinity: The Perfect 1:7 Synergy

Stony corals constantly consume alkalinity (carbonate hardness) and calcium to build their calcium carbonate ($CaCO_3$) skeletons. To sustain this calcification, corals require approximately 7 mg of calcium for every 1° dKH of alkalinity. Because they are consumed in this fixed biological ratio, maintaining a balanced aquarium requires replacing them in kind.

The Nyos® ION-B Advantage

We engineered the Nyos® ION-B system around this exact ratio. By dosing equal amounts of the ALK/pH+ and Ca/Mg+ solutions, you automatically add alkalinity and calcium in their ideal 1:7 proportion. While individual tank metabolism can vary slightly, our balanced formulation simplifies dosing routines and ensures optimal, predictable conditions for coral growth.

2. Preventing Ion Shift

In many traditional two-part methods, calcium and carbonate are added via calcium chloride and sodium (bi)carbonate. Over time, the leftover sodium and chloride ions accumulate, causing a gradual shift in the overall seawater matrix—a phenomenon known as ion shift.

This imbalance degrades water quality, depletes critical elements like sulfate or potassium, and often triggers "old tank syndrome." While frequent water changes can dilute this effect, they cannot prevent it.

The Nyos® Solution

The Nyos® ION-B method entirely bypasses this issue. Although the process still creates additional sodium chloride, our formula instantly delivers the exact matching ions (such as sulfate and potassium) during the dosing process. This ensures constant ion balancing and a permanently stable seawater matrix.

3. Advanced pH Stabilization

Maintaining a stable pH between 8.0 and 8.3 is absolutely vital for coral vitality. Traditional sodium bicarbonate systems often suffer from a sharp pH drop of up to 0.5 units at night—a stress factor that can cause sudden coral tissue loss and bleaching overnight.

Nyos® ION-B ALK/pH+ acts as both a carbonate supplement and a powerful pH stabilizer. It actively maintains your aquarium water within the ideal 8.0–8.3 range, eliminating dangerous nocturnal pH drops and providing your reef with a highly stable environment.

4. Next-Gen Trace Element Integration

Modern ICP-OES water analysis has revolutionized our understanding of trace element consumption, revealing exactly which elements corals need and the precise ratios they consume. Essential trace elements like vanadium, rubidium, and selenium are frequently overlooked in standard reef keeping, while volatile elements like iron and zinc rapidly drop out of solution if not properly protected.

The Nyos® ION Elements series (1 Ca/Mg, 2 Ca/Mg, and 3 ALK/pH) bridges this gap:

• Consumption-Based Blends: Formulated using real-world data from high-demand modern reef systems.

• Full-Spectrum Coverage: Delivers a comprehensive suite of all critical trace elements, including vanadium, selenium, and rubidium.

• Bioavailable Stability: Volatile elements like iron and zinc are molecularly stabilized to remain directly accessible to corals.

• Seamless Dosing: Easily tailored to your system's specific demands by adding them directly into your Nyos® ION-B Ca/Mg+ and ALK/pH+ base solutions.

5. Nyos® ION-B vs. Traditional Balling (Two-Part) Methods

Standard two-part methods rely strictly on dosing raw calcium chloride dihydrate and sodium hydrogen carbonate. This classic approach presents several distinct disadvantages compared to the modern Nyos® ION-B system:
