COLOMBO - Marine Testlab KH-CA-MG-NO3-PO4

Complete marine aquarium test kit for precise water monitoring

The COLOMBO Marine Testlab KH-CA-MG-NO3-PO4 was designed for those who want complete control of their seawater parameters without the need for multiple separate kits. In a marine aquarium, certain indicators are essential: KH for stability, calcium and magnesium for overall tank balance, and nitrates and phosphates to monitor nutrient levels. This kit brings together everything you need to track these values in a single, coherent, practical, and easy-to-use set. It's a true foundation for maintaining a clean, stable, and well-managed tank on a daily basis.

COLOMBO Marine Testlab: five essential tests in a single case

This kit contains professional drop tests for measuring five key parameters in marine aquariums: carbonate hardness (KH) , calcium (Ca) , magnesium (Mg) , nitrates (NO3) , and phosphates (PO4) . This selection is far from arbitrary. These values are among the most closely monitored when an aquarist wants to maintain well-balanced water and precisely adjust their maintenance routine. By combining these measurements in a single kit, Colombo offers a clear and well-designed solution that eliminates the need for scattered equipment and makes monitoring much more natural within the maintenance routine.

An ideal kit for monitoring KH, calcium, magnesium, nitrates and phosphates

The major advantage of this Colombo Marine Testlab is that it covers all the essentials for monitoring a marine aquarium. KH helps monitor water stability, calcium and magnesium contribute to the tank's chemical balance, while NO3 and PO4 allow you to control nutrients related to water quality and prevent imbalances. For a reef aquarium, this type of monitoring is particularly useful, as it allows you to better track coral growth and coloration. For a fish-only tank, it remains just as valuable for maintaining consistently clean water over time.

A practical, organized and easy-to-use rigid case

The rigid carrying case format offers real convenience. All the equipment is neatly organized, structured, and easy to store. Tests are clearly labeled, accessories are readily available, and the whole kit is easy to transport and store. This detail makes a big difference in practice, as a well-organized kit immediately motivates you to regularly monitor your water parameters. The included visual instructions also make operation smoother, allowing even a beginner aquarist to get started without difficulty. Everything is designed to make water monitoring simpler, faster, and more enjoyable.

Colombo liquid tests are renowned for their accuracy and reliability.

Colombo liquid tests are valued for their precision and reproducibility . They provide reliable readings of measured values, which is essential when adjusting supplements, correcting imbalances, or verifying the effect of a water change. The goal is not simply to have a number, but to be able to rely on it to make informed decisions. With this kit, the user has a solid foundation for managing aquarium maintenance more accurately, without having to juggle different test formats or brands.

40 tests per parameter and rechargeable to extend usage

Each test kit in the case allows for up to 40 analyses , providing excellent autonomy for regular monitoring. This format is particularly appealing to aquarists who like to monitor their parameters over time without having to replace their equipment too frequently. And when some reagents run out, there's no need to replace the entire kit: Colombo seawater tests can be refilled individually . This system makes the kit even more practical and economical, as it allows you to extend its use without having to start from scratch.
