How to Create a Liquid Remineralizer?

Liquid remineralizers are very convenient to use and provide precise dosing. Especially useful for automatic top-off systems or with frequent small water changes. In this guide, we'll create a low-concentration liquid remineralizer with a volume of 1000 ml.

Step-by-Step Guide

Step 1: Open the Remineralizer Creation Form

  1. Go to the "Remineralizers" section

Step 2: Select Reagents

  1. In the reagent list, be sure to select "Water - H2O"

  1. Add active components:
    • Calcium chloride dihydrate - CaCl2(H2O)2
    • Magnesium sulfate heptahydrate - MgSO4(H2O)7

Important: The system will determine the remineralizer type as liquid only when water is included in the composition.

Step 3: Set Remineralizer Solution Parameters

We want to have the following parameters when adding 200 ml of remineralizer to 10 L of water: Gh = 6, Ca/Mg = 4.

  1. In the Dosage field, specify "200" ml instead of 10 ml.

  1. In the Water-H2O field, enter "1000" ml.

  1. In the Total GH field, enter the value "6".

  1. In the Ca/Mg ratio field, enter the value "4".

  1. The system will calculate the required masses of all reagents to dissolve in 1 L of water.
    • Calcium chloride: 5.73 g
    • Epsom salt: 3.85 g
  2. Check the Ca concentration value in the "Solute concentration" section. It should be less than 2 to prevent calcium from precipitating as calcium sulfate. In our recipe, Ca concentration equals 1.52 g/L (optimal value).

Important: If precipitate has formed, thoroughly shake the solution before use and measure the required portion. The precipitate will completely dissolve in the aquarium within a few hours.

Step 4: Save with Detailed Description

  1. In the Name field, enter "Liquid remineralizer".
  2. Add a description if desired.

Practical Recommendations

Pay attention to system warnings:

  • If using poorly soluble salts (e.g., gypsum), the system will warn about possible precipitation
  • When solubility is exceeded in calculations, a warning about maximum concentration at 25°C will appear

Advantages of Liquid Remineralizers

  • Convenience: Ready for immediate use
  • Precision: Easy and accurate dosing
  • Automation: Suitable for auto-dosers

Limitations

  • Precipitate: Some reagents may interact with each other and precipitate
  • Storage: Requires more storage space
