Why analyzing your reverse osmosis water is essential in reef aquariums
In reef aquariums, the quality of reverse osmosis water is the foundation of the entire tank's balance. Even with a high-performance reverse osmosis system, traces of heavy metals, silicates, or other pollutants can remain if maintenance is not optimal. These contaminants, invisible to the naked eye, can promote unwanted algae growth, disrupt coral growth, or create chronic imbalances.
ICP PURA acts as an independent quality control system. It allows you to verify the actual efficiency of your reverse osmosis system and deionizing cartridges. If a problem is detected, you can take immediate action: membrane replacement, resin change, or checking the pressure or quality of the incoming water.
The result: perfectly controlled water, a healthy base for your reef salts and lasting stability in your aquarium.
How does PURA ICP analysis work step by step?
An analysis performed using Spectrogreen ICP-OES technology
All Zoanthus Lab analyses are performed using a Spectrogreen ICP-OES spectrometer , a high-precision instrument used in many professional laboratories. This inductively coupled plasma optical emission technology enables the detection of extremely low concentrations of dissolved elements with high reliability and excellent reproducibility.
In practice, the sample is injected into a plasma heated to a very high temperature. The elements present then emit a specific light signature, which the Spectrogreen analyzes with precision. This method allows for the simultaneous measurement of numerous elements, even in trace amounts, thus guaranteeing a complete and rigorous reading of the purity of your reverse osmosis water .
All Zoanthus Lab analyses are performed in our laboratory in Saint-Étienne , with a strong commitment to rigor and reliability. Each sample is processed by qualified technicians , experienced in the demands of reef aquariums, to guarantee consistent, precise, and perfectly usable results for monitoring your aquarium.
What parameters are controlled with ICP PURA?
ICP PURA focuses on detecting undesirable elements that may remain in RO/DI water. The goal is not to measure classic reef parameters, but to ensure that the water is truly pure before any use.
The analysis allows us to detect, in particular:
- Traces of metals (copper, zinc, iron…)
- Silicates responsible for brown algae
- Mineral residues associated with a worn membrane
- Potential pollutants from the water supply
This check is particularly recommended in the event of:
- Unexplained algal bloom
- Recent change of membrane or resin
- Doubts about the quality of the mains water
- Setting up a new reef tank

Clear results for immediate decisions
PURA ICP results are presented in a clear and structured manner. If a contaminant is detected, you can quickly identify the likely source of the problem and take immediate action. This prevents the introduction of unwanted elements into your tank during water changes or salt preparation.
Combined with Zoa Aqua Manager , the analysis allows you to centralize your data and track the evolution of your reverse osmosis water quality over time. This lets you visualize the effectiveness of your maintenance and anticipate when to replace consumables.
ICP PURA: Safety first
A successful reef aquarium relies on an impeccable foundation. Before adjusting supplementation or optimizing coral growth, it is essential to ensure that the water used is perfectly pure.
ZOANTHUS LAB - ICP PURA is the ideal tool to secure this crucial step. Simple to use, precise, and designed for demanding aquarists, it provides true peace of mind. Controlled water means a more stable, healthier, and longer-lasting reef.
