Reef Zlements ICP testing is an affordable way to get in depth water analysis for your reef aquarium.

Water quality is extremely important and especially if you keep corals. If you are trying to reduce water changes, ICP tests along with complete dosing are necessary to make sure that your water parameters are in balance.

A few words from Reef Zlements

Our ICP tests are used in conjunction with the company’s own in-house SPECTROGREEN DSOI ICP-OES machine. This allows reefers to achieve the highest water quality possible.


The Reef Zlements SPECTROGREEN DSOI unique radial dual side-on interface provides twice the sensitivity of conventional radial views and it equals the sensitivity of newer vertical-torch dual-view systems.

Reef Zlements ICP testing gets an accurate picture of your aquarium water in 5 easy steps!

Step 1: Register for a Reef Zlements ICP account

Once you have your ICP test you can register for a new account by clicking here and filling in the registration form. When your account is registered you can login at any time to check on your test results or register a new test. Reef Zlements will inform you by email as soon as your test results are ready to view.

Step 2: Enter your aquarium details

In each Reef Zlements ICP analysis kit you will receive bar codes. Enter these barcodes, along with your tank name and aquarium water volume in litres. This helps Reef Zlements to give you recommendations to achieve the best water quality once the test is completed. For the most accurate advice following your test, enter the true water volume of your set up. Remember to minus the rock, sand and equipment displacement from the total aquarium volume.

Step 3: Stick the barcodes to the vials

The barcodes are easy to stick onto the vials. There is a white rectangle printed on each vial that shows the ideal place to put the barcodes onto the tube.

There are two barcodes that are the same. These are for your two saltwater vials. This is one test, so take them both from the same aquarium display.

Step 4: Taking a sample

Rinse the 2 saltwater vials 2 – 3 times with your aquarium water to be tested and then fill with with your saltwater.

The third vial is for your RODI sample. Again, rinse it with your RODI water before filling it.

Make sure that the vial caps are screwed on tightly.

Once you have taken the samples, pop your samples into the envelope and seal with the adhesive strip.

Step 5: Post the vials

Depending on how quickly you would like your test back, choose what service best suits you for sending the samples.

You will need at least a large letter stamp. Better still, pop into your local post office or look online to find other ways to send your test.

Here at Cornwall Aquatics, we usually send our samples to Reef Zlements by Royal Mail on their 1st class large letter service. It is best to send early in the working week. This way you will tend to get your result quicker.

If it is an emergency test, you may want to send it next day guaranteed delivery.

If you are happy to wait a little, the Reef Zlements ICP tests can be sent 2nd class, the extra time does not degrade the samples and Reef Zlements are still fairly quick to process the samples.

It’s totally up to you!
