Tropic Marin ICP Water Analyses PLUS - 1 Pack

Take full control of your reef with the most complete water analysis Tropic Marin offers. The ICP Water Analyses PLUS sends two samples to the Tropic Marin waterLAB: your aquarium seawater and your reverse osmosis (RO/DI) source water. Both are run through inductively coupled plasma (ICP-OES) analysis for a detailed breakdown of the major, minor, and trace elements in each. That side-by-side view lets you pinpoint whether an issue is building up inside your tank or slipping in through your top-off and mixing water. This listing is the 1 Pack, a single PLUS analysis. If you only need your display water checked, the standard ICP 1 Pack covers that, and you can browse our full water testing and salt mixes selections for the rest of your routine.

How It Works

1. Each PLUS pack includes two sample vials and a prepaid return mailer.
2. Fill one vial with aquarium water and the other with your RO/DI (reverse osmosis) water.
3. Register your samples online and mail them to the Tropic Marin waterLAB.
4. Receive a detailed report by email, usually within a few days of the lab receiving your samples.
5. Follow the clear recommendations to fine-tune your source water, salt mix, and dosing.

Why Test Your Source Water Too

Your reverse osmosis water is the foundation of every water change and top-off. If phosphate, silicate, copper, or other contaminants slip past a tired RO membrane or spent DI resin, they end up in your tank no matter how careful your dosing is. The PLUS analysis checks that source water directly, so you know whether to replace filter media before those elements ever reach your corals.

What the Analysis Covers

Using ICP-OES, the Tropic Marin waterLAB measures roughly 40 elements in each sample, including:

• Major elements such as calcium, magnesium, sodium, potassium, and sulfur.
• Minor and trace elements such as strontium, boron, iodine, and lithium.
• Pollutants and heavy metals such as copper, aluminum, and phosphorus that can stress sensitive livestock.

Your report turns the raw numbers into clear, actionable recommendations for your specific system.

Frequently Asked Questions

What does PLUS add over the standard ICP analysis?
The PLUS pack analyzes a second sample, your reverse osmosis source water, alongside your aquarium water, so you receive two full ICP reports instead of one.

Why should I test my RO/DI water?
Source water is the base for every water change and top-off. Testing it shows whether contaminants are entering the tank through your filtration before they affect livestock.

How long do results take?
The waterLAB emails your report, typically within a few days of receiving your samples. Total time depends on mailing.

Is this for freshwater or saltwater?
It is designed for saltwater and reef aquariums. The seawater analysis is calibrated for marine parameters.
