Step 3
Our molecular scientists sequence the DNA in the sample. A detailed, easy-to-read health report is sent directly to your email.
A single outbreak of Marine Velvet or Ich can wipe out prized fish collections in a matter of days.
Treatments, stress, and unstable tank conditions can impact the health of your entire ecosystem, not just infected fish.
Getting rid of a disease outbreak often means quarantine tanks, medication protocols, repeated testing, and weeks (sometimes months) of rebuilding.
Marine livestock represents hundreds or thousands of dollars in investment, not to mention the countless hours spent building a thriving reef.
The HealthScan qPCR Test helps identify invisible pathogens before they become visible problems.
Standard aquarium test kits only look at basic chemical levels like ammonia or nitrates. They cannot tell you if a lethal parasite is currently swimming in your water column, threatening your livestock.
Parasites like Marine Velvet can infect a fish's gills and cause death before a single white spot ever appears on its skin. HealthScan finds their literal DNA footprint early.
No more holding tiny plastic vials up to a paper color chart trying to guess a shade of pink. Our qPCR laboratory assays deliver digital, objective, and definitive results.
Adding one unquarantined fish or coral can accidentally introduce pests that wipe out thousands of dollars in livestock. Use HealthScan as your ultimate quarantine gatekeeper.

I found Dx Aquaria through a random YouTube video from a trade show back in 2025. Unfortunately, it was after my first tank crash from ich. Since then, I have been a regular customer, and Dx Aquaria has been invaluable to me on multiple occasions.
One example was when I had fish in my quarantine system that were constantly itching. Fortunately, the PCR tests showed they did not have ich. We eventually traced the problem to an aquarium decoration that was leaching resin into the water and irritating the fish.
Dx Aquaria also helped me diagnose an ich and fluke outbreak in my main display. It turned out I had both at the same time. During treatment, they performed weekly PCR tests to monitor the parasite load while I treated my FOWLR display with copper.
As I continue in the hobby and move forward with my 300-gallon FOWLR system, I won't hesitate to send in samples whenever I suspect something is wrong. The peace of mind and information these tests provide are invaluable.
Dx Aquaria has been a great company to work with, and I can't recommend them highly enough. All of my testing has been done using their PCR mail-in service.
As a reef hobbyist, I’ve spent a lot of time and money building my aquarium, and dxAquaria has become one of the tools I rely on most. The qPCR testing has helped me identify potential pathogen concerns that I never would have known existed otherwise, allowing me to make better decisions about quarantine, treatment, and stocking.
The biggest value for me is confidence. Instead of guessing, I have actual data to work from. That peace of mind alone is worth it.
Nick has always been incredibly responsive and helpful whenever I’ve had questions about my results. The level of customer support has been exceptional.
I would highly recommend dxAquaria to any serious reef keeper who wants to better understand what’s happening in their system and protect their livestock.
I use the QPCR tests as a "value added" part of my quarantine process when doing custom full quarantine orders for customers. Whether there are six figure stock lists in their system, or they are adding the first fish to their systems, the QPCR tests give myself and the customer an added level of confidence and peace of mind.
There is really no room for error when doing full quarantine orders and the fast shipping and fast processing on these tests help me get fish shipped to customers sooner rather than later in an already lengthy quarantine process.
Nick has always responded promptly to any questions and when I first began using them spent quite a bit of time breaking down all the "ins and outs" of the test and how it works.
There are fewer and fewer businesses in this hobby providing quality customer service and dxAquaria crushes it. I cannot recommend the tests enough to anyone regardless of being a beginner or advanced aquarist, especially those looking to confirm a quarantine protocol success or failure.
Ultimate Peace of Mind for My Reef tank:
Anyone in the reef-keeping hobby knows that the underlying fear of an invisible parasite outbreak is always there. After investing so much time, effort, and money into my tank, I started using DXAquaria to get an accurate look at what’s actually happening in my water column. I continue to use it as part of my regular quarantine and maintenance routine because it takes the guesswork completely out of tank health.
Catching things like Velvet, ich or Uronema before they show physical symptoms saves fish lives and protects my financial investment. Instead of staring at my tank wondering if a fish is flashing or just acting weird, I have hard, scientific data. That relief is worth every penny.
Because this involves sending samples out and waiting for data, communication is everything. Nick and his team has been exceptional. The instructions are foolproof, the turnaround time is better than promised, and the way they break down the final report makes complex data easy to understand. Whenever I’ve had a question about my results, Nick has been incredibly knowledgeable and responsive.
If you have a reef tank, you shouldn’t wait for a crash to start testing. I highly recommend DXAquaria to any hobbyist who wants to proactively protect their reef rather than just reacting to disasters.
No. Our collection vials contain a specialized stabilizing buffer that instantly preserves the pathogen DNA, ensuring it arrives at our lab perfectly intact regardless of shipping times.
The HealthScan qPCR test is currently optimized specifically for marine (saltwater) and reef aquarium setups to target the most common marine parasites.
Your digital report won’t just give you data. It will include references to the best quarantine and treatment protocols to help save your tank.
