PRODIBIO Start Up Nano 2 ampoules is a complete kit specifically designed to quickly set up a nano aquarium while ensuring a smooth start-up. Suitable for both freshwater and saltwater tanks, it combines one ampoule of BioDigest Start, which provides live bacteria capable of rapidly initiating the nitrogen cycle, and one ampoule of Stop Ammo Start, formulated to capture the nitrogen contained in ammonia and transform it into harmless compounds. This dual action provides more stable biological filtration from day one , even in a small volume that is highly sensitive to fluctuations. It's the ideal solution for starting a nano tank cleanly, quickly, and with much greater peace of mind.
The PRODIBIO Start Up Nano 2-bulb kit was designed to meet the very specific needs of small aquariums. In a nano tank, everything happens faster. Parameters fluctuate more easily, imbalances appear more quickly, and the startup phase requires even more care than in a larger tank. This kit simplifies this step by providing a clear, practical, and perfectly sized solution.
It combines BioDigest Start and Stop Ammo Start in a single package, two complementary products that work together from the moment the tank is filled. The first quickly establishes beneficial bacterial activity, while the second helps neutralize ammonia, one of the primary risks in a new aquarium. This combination allows you to start off on a healthier footing, with a nano aquarium better prepared from the very first hours.
In Start Up Nano, BioDigest Start provides naturally occurring nitrifying, denitrifying, and facultative bacterial strains selected for their ability to quickly initiate the nitrogen cycle. These bacteria begin working as soon as they come into contact with oxygen in the water. There's no long wait, no complicated reactivation, and that's precisely what makes all the difference when starting a small aquarium.
Their role is essential in the transformation of ammonia into nitrites, then nitrites into nitrates, before pushing the process towards nitrogen. This gradual process allows for the establishment of efficient and stable biological filtration much more quickly. In a nano aquarium, where the slightest imbalance can be felt almost immediately, this rapid start-up is a real advantage to avoid a shaky beginning.
The second component of the kit, Stop Ammo Start, secures this critical phase thanks to a formula based on specific plant extracts. Its role is to trap the nitrogen contained in the ammonia and transform it into harmless compounds. In a nano aquarium, this action is particularly valuable, as small volumes react quickly and are less tolerant of pollution spikes.
Stop Ammo Start also helps reduce nitrite production during the initial setup, making the process smoother and cleaner. It acts as immediate protection while beneficial bacteria establish themselves in the tank. This dual protection is ideal for aquarists who want to start a small aquarium without leaving too much room for improvisation.

The advantage of Start Up Nano 2 ampoules lies in the perfect complementarity between its two components. BioDigest Start quickly establishes the bacteria necessary for biological filtration, while Stop Ammo Start helps control ammonia from the very first hours. The two products work together seamlessly, allowing for a faster and safer start-up .
In a small tank, this approach is particularly relevant. A nano aquarium doesn't tolerate mistakes. By combining bacterial seeding and ammonia protection in a single kit, PRODIBIO offers a simple, effective, and reassuring solution for quickly establishing the foundations of a stable tank. It's exactly what you need to start a small aquarium methodically.
Start Up Nano is primarily used when setting up a new nano aquarium , whether freshwater or saltwater. It helps establish a reliable biological base more quickly and ensures water quality from the very first hours of operation. In freshwater, it allows for the faster introduction of the first hardy inhabitants. In saltwater, it also helps shorten this sensitive phase while maintaining a cautious approach.
The kit can also be useful during a renovation or partial reset of a small aquarium . After a thorough cleaning, a major change in decor, or a complete overhaul of the tank, it allows for a cleaner restart of the biological dynamics. It's a very practical solution for getting back on track without complicating the maintenance of a small tank.
The Start Up Nano 2-ampoule version corresponds to the Nano range for aquariums from 0 to 60 liters . It contains one ampoule of BioDigest Start and one ampoule of Stop Ammo Start. This packaging is perfectly suited to very small volumes, where a precise, easy-to-use, and well-calibrated solution is needed to avoid any unnecessary guesswork.
Each BioDigest ampoule can treat up to 1000 liters, while each Stop Ammo ampoule treats up to 200 liters, but in this kit, the proportions have been carefully considered to properly support the initial setup of a nano aquarium. The ampoule format is particularly practical for this type of setup: it allows for clean, quick, and reliable use, without risky overdosing or wasted time.
| How to use it? | What volume? | What dosage? |
|---|---|---|
| Starting a nano aquarium with live bacteria and ammonia protection | 0 to 60 liters | Box of 2: 1 BioDigest Start + 1 Stop Ammo Start |
| Restarting a small tank after a major cleaning or reset | 0 to 60 liters | Use the complete kit according to the tank's volume. |
| Introduce the first robust inhabitants gradually after stabilization | Fresh water or sea water | After approximately 4 hours in fresh water and 12 hours in seawater |
With its compact size, well-designed dual action, and ease of use, the PRODIBIO Start Up Nano 2 bulbs is an excellent choice for aquarists who want to start a small tank cleanly and without unnecessary stress . It perfectly meets the needs of nano aquariums, where even the slightest variation matters and stability must be established quickly.
This kit naturally finds its place among the essentials for starting a new aquarium, because it allows you to establish a more secure biological foundation from the very beginning. For a first nano aquarium, a small marine project, or restarting after renovation, the Start Up Nano 2 bulbs offer a simple, reassuring solution that is truly suited to small volumes.
