Marine aquarium calcium test: precise control for better-balanced water
The COLOMBO Calcium Test Basis was designed for aquarists who want to reliably monitor calcium levels in their saltwater aquarium without any hassle. In a marine aquarium, this parameter is one of the values closely monitored, and it's essential to have a test that is easy to read, consistent, and reproducible. This kit uses a titration method , known for its accuracy, with a clear color change that helps you identify the result with greater confidence. Thanks to its convenient format and included accessories, it allows for regular tank monitoring, whether for routine maintenance or when water quality adjustments are necessary.
COLOMBO Ca-Calcium Test Basis: a clear and simple titration method to use
This test uses a step-by-step procedure that is easy to learn. First, 5 ml of water is taken, then 5 drops of the Ca-1 reagent are added. At this stage, a white deposit typically appears at the bottom of the test tube. Next, adding one measure of Ca-2 powder transforms the sample into a dark red to purplish-red color. The final step involves slowly adding the Ca-3 liquid using the 1 ml syringe and its tip. As the liquid is added, the color changes until it turns blue . This transition marks the reading point. The procedure is simple, logical, and pleasant to perform, especially for those who like to feel in control during the analysis.
Measure calcium in your aquarium accurately with a reliable reading
The major advantage of this test is its precise reading. The amount of Ca-3 liquid used to change the color from purplish-red to blue allows you to directly determine the calcium concentration using the provided table. For those who prefer an immediate numerical reading, the calculation remains very simple: just multiply the volume used by 500. For example, if 0.7 ml is needed to achieve the color change, this corresponds to 350 mg of calcium per liter . This method offers a concrete, precise, and easy-to-verify reading. It is ideal for aquarists who want to monitor their water parameters carefully, rather than relying on a vague approximation.

A complete calcium test kit with accessories included for approximately 40 tests
The COLOMBO Calcium Test Basis also stands out for its practicality. The kit contains everything you need to get started quickly: reagents, test tubes, and accessories are all included to make the test more convenient to perform. Depending on the calcium level measured over time, the contents allow for an average of 40 tests . This makes it a suitable choice for long-term monitoring, without needing to replace the equipment too frequently. For even greater ease of use, this test can also be simplified with the Colombo test stirrer , an accessory designed to make handling even smoother.
Instructions for use for a regular and accurate Colombo calcium test
To obtain a clean and consistent result, a few simple habits truly make a difference. The test tube must be perfectly clean before use and cleaned immediately after the test. The volume of water taken must be as precise as possible, as the quality of the measurement depends directly on it. While adding the drops, the bottle must be held perfectly vertical , without tilting, and air bubbles in the drops should be minimized. Regarding the Ca-3 reagent syringe, the presence of an air bubble above the liquid is normal: it serves to compensate for the volume in the tip and should not be interpreted as a filling error. With these few steps, the test becomes more consistent and a truly reliable monitoring tool for the marine aquarium.
Why choose the COLOMBO calcium test?
This calcium test kit for marine aquariums ticks all the right boxes: accuracy , clear readings , good battery life , and ease of use . It's ideal for both the meticulous aquarist who likes to closely monitor their parameters and those simply looking for a reliable test without unnecessary complications. It naturally takes its place among the essential tools for monitoring saltwater. With its effective titration method and included accessories, the COLOMBO Ca-Calcium Test Basis is a dependable choice for maintaining regular calcium monitoring and keeping a clear picture of your tank's health.
