With ZOANTHUS LAB - ICP PURA , you can finally control the true quality of your reverse osmosis (RO/DI) water . Before even considering calcium, magnesium, or trace elements, everything starts with a healthy base. This ICP analysis is specifically designed to verify the purity of your preparation water and detect invisible contaminants that can disrupt your reef aquarium.
A worn membrane, depleted resin, or a poorly maintained filter can allow unwanted elements to pass through. ICP PURA precisely identifies these issues to ensure your water is safe before remineralization. Compatible with Zoa Aqua Manager , it translates results into concrete decisions for maintaining a stable and healthy reef.
With ZOANTHUS LAB - ICP MAX , you take your aquascaping to the next level: an ultra-comprehensive analysis designed for demanding aquarists who want to understand everything happening in their tank … and also secure their foundation with RO/DI water testing. This formula combines in-depth reef analysis (major elements, nutrients, trace elements, and micronutrients) with an expanded spectrum including additional parameters such as fluoride , and dedicated RO/DI water quality testing.
ICP MAX allows for earlier, more precise, and more accurate detection of issues: slow accumulation of an element, subtle metal contamination, unbalanced supplementation, or imperfect starting water. The results are clear, actionable, and, most importantly , compatible with the free Zoa Aqua Manager calculator , transforming the analysis into concrete and personalized recommendations.
The REEF ICP analysis is designed for aquarists who want to maintain control over their reef tank without overcomplicating things. It covers all the major elements (such as calcium, magnesium, and potassium) as well as the trace elements essential for coral growth and coloration. With just one sample submission, the user receives a detailed snapshot of their water's actual condition.
This type of analysis allows you to identify problems before they become serious . A low nutrient level, an accumulation of another, insidious contamination—everything is clearly shown in the report. The result: targeted, precise, and above all, effective adjustments. The tank remains stable, corals grow better, and unpleasant surprises are minimized.

Marine ICP analysis is performed using a Spectrogreen ICP-OES spectrometer , a high-precision instrument used in many professional laboratories. This inductively coupled plasma optical emission technology allows for the highly accurate measurement of major and trace elements present in reef water , even at extremely low concentrations.
In practice, the aquarium water sample is injected into a plasma heated to a very high temperature. The dissolved elements then emit a unique light signature, which the Spectrogreen analyzes and interprets with remarkable precision. This method allows for the simultaneous measurement of a wide spectrum of elements, guaranteeing a complete, reliable, and reproducible snapshot of the actual condition of your reef tank .
All Zoanthus Lab analyses are performed in our laboratory based in Saint-Étienne , with a genuine commitment to the quality and consistency of measurements. Each sample is processed by qualified technicians specializing in reef aquariums to provide accurate, usable results tailored to the requirements of a modern marine aquarium.

The ICP MARIN analysis was designed to provide a complete and accurate view of the chemical balance of a reef aquarium. Unlike an analysis dedicated to reverse osmosis water, here the objective is to measure all the major, minor, and trace elements that directly influence the health, growth, and coloration of corals.
The MARINE ICP monitors more than 40 essential parameters , including:
This detailed analysis allows us to:
Thanks to its comprehensive analysis of over 40 parameters, the MARINE ICP becomes a true management tool. It provides a clear, precise, and actionable view for maintaining a stable, high-performing, and sustainable reef aquarium .
| Analysis | Number of parameters | Specifics | Ideal for |
|---|---|---|---|
| ICP MARIN | over 40 | Major elements + essential trace elements | Regular monitoring of a reef aquarium |
| ICP MAX | + over 45 + reverse osmosis water | Extended spectrum: fluoride, nitrates, KH, RO water analysis | Demanding aquarists and thorough diagnosis |
| ICP PURA | Specifically for reverse osmosis water | Contaminant control and RO/DI water quality | Checking the preparation water before remineralization |

Every analysis performed by Zoanthus Lab is designed for immediate use. The data obtained can be integrated into the free Zoa Aqua Manager calculator , allowing for precise and personalized dosing based on the actual tank volume and measured variations. No more manual calculations or guesswork: everything is clear, structured, and immediately actionable.
This compatibility transforms a simple analysis into a true management tool. Users can correct a deficiency, reduce an excess, or adjust their supplementation with a coherent logic. Monitoring becomes regular, measured, and above all, controlled.

Of the three packages offered, ICP MARIN represents the ideal compromise. Comprehensive enough to monitor the essentials, it avoids information overload for routine maintenance. It is perfectly suited to those who want serious control of their reef tank while maintaining a practical approach.
Whether it's to verify stability, understand a slowdown in growth, or simply ensure periodic monitoring, this analysis provides a solid foundation. It brings visibility, rigor, and above all, peace of mind.


Zoanthus Lab Iodine 250 ml is a concentrated solution designed to precisely correct iodine deficiencies in marine reef aquariums. Iodine (I) is an essential trace element involved in numerous biological processes in soft corals, crustaceans, and microfauna. Formulated with purified water and pharmaceutical-grade sodium iodide , this supplement guarantees a stable, clear, and perfectly measurable concentration. Free of unnecessary chelators and stabilizers, it integrates ideally into ICP- based management systems. A simple, precise, and transparent approach for optimal control of your reef tank.

PRODIBIO BioDigest 30 ampoules is a concentrated bacterial solution designed to help aquariums regain efficient biological filtration and visibly healthier water. Suitable for both freshwater and saltwater aquariums , this treatment utilizes several strains of live bacteria that work together to support the tank's natural cycle. It contributes to the digestion of organic waste, the reduction of undesirable compounds, and improved overall environmental stability. Highly useful for setting up a new aquarium, after an imbalance, or for regular maintenance, BioDigest helps limit nitrites, reduce nitrates and phosphates , and curb the proliferation of filamentous algae for a cleaner, more stable, and more pleasant aquarium to maintain.
Fleece-Roll 500 from Red Sea is a roll of high flow 50gsm non-woven polyester filter fabric , for the ReefMat 500 filter . Compatible with skimmers. The roll has a length of 28 m and a width of 11.3 cm.
ZOA Bacter is a concentrate of non-pathogenic live bacteria fixed on a maerl substrate, designed to stabilize the biological balance in both saltwater and freshwater aquariums. Its multi-strain consortium naturally competes with unwanted algae, lowers nitrates and phosphates through assimilation, and transforms organic deposits into resources for filtration. Result: cleaner windows, clear water and a healthier biotope. Fish and corals regain vitality and resistance (protection against vibrioses), while a beneficial biofilm is established to feed certain invertebrates. Compatible with skimmers and filters, the effect is quickly seen, especially with correct mixing. 40 ml bottle (34 g) – 10 9 CFU/g , GMO-free, no risk of overdose .
