Remineralization Calculator

Calculate the exact amount of remineralizer to add to your RO water for perfect shrimp parameters every time.

How to Use This Calculator

Step-by-Step Guide

  1. 1

    Enter the volume of water you're preparing (in gallons or liters)

  2. 2

    Enter the current TDS of your starting water (usually 0 for RO/DI water)

  3. 3

    Enter your target TDS (check our TDS guide for species-specific ranges)

  4. 4

    Select your remineralizer product from the dropdown

  5. 5

    Click Calculate to see how much remineralizer you need

Recommended TDS Ranges

Neocaridina 150-300 ppm

Cherry Shrimp, Blue Dream, etc.

Caridina 100-150 ppm

Crystal Red, Taiwan Bee, etc.

Sulawesi 150-250 ppm

Cardinal, Harlequin, etc.

How the Formula Works

This calculator uses product-specific dosing ratios to determine the exact amount of remineralizer needed:

TDS Increase Needed = Target TDS - Current TDS

Grams Needed = (TDS Increase / TDS per Gram) x Water Volume

Teaspoons = Grams / 3 (approximate)

Each remineralizer product has a different concentration and mineral composition, which is why we maintain a database of TDS-per-gram ratios for popular products like Salty Shrimp, SL-Aqua, Glasgarten, and Dennerle.

For best accuracy, we recommend using a digital scale rather than measuring scoops. Product scoops can vary in how much powder they actually hold depending on how you scoop and pack the powder.
