Seachem Flourish Excel is a popular liquid carbon supplement specifically formulated for planted aquariums. It serves as an alternative to injected CO2 systems, providing aquatic plants with a readily available source of carbon essential for photosynthesis and growth.

Here are some key details about Seachem Flourish Excel:

  1. Liquid Formulation: Flourish Excel comes in liquid form, making it easy to dose directly into the aquarium water. This allows for precise control over carbon supplementation and ensures that plants receive a consistent supply of carbon.

  2. Carbon Source: The primary function of Flourish Excel is to provide a readily available source of carbon for aquatic plants. Carbon is an essential element for photosynthesis, the process by which plants convert light energy into chemical energy to fuel growth. By supplementing with Flourish Excel, aquarium plants can thrive and exhibit lush, healthy growth.

  3. Algae Inhibition: In addition to promoting plant growth, Flourish Excel also helps inhibit the growth of algae in the aquarium. The carbon provided by Flourish Excel can outcompete algae for resources, helping to prevent algae blooms and maintain a clean, algae-free environment.

  4. Compatibility: Flourish Excel is suitable for use in both freshwater and planted aquariums containing a variety of aquatic plants. It is compatible with most species of aquarium plants, including delicate and demanding species.

  5. Usage: Flourish Excel is typically dosed directly into the aquarium water according to the manufacturer's recommendations. The dosage may vary depending on factors such as the size of the aquarium, the density of plants, and the desired level of carbon supplementation. It is recommended to start with a lower dosage and gradually increase as needed while monitoring plant growth and algae levels.

  6. Plant Health Benefits: With regular use, Flourish Excel can promote vibrant plant growth, improve leaf coloration, and enhance overall plant health. It can also help stimulate the growth of new shoots and roots, leading to denser and more lush aquarium landscapes.

  7. Nutrient Supplement: While Flourish Excel primarily serves as a carbon supplement, it also contains other nutrients and trace elements that are beneficial for plant growth. These additional nutrients help ensure that plants have access to all the essential elements required for healthy growth and development.

Seachem Flourish Excel is generally considered safe for shrimp when used as directed. However, there are a few considerations to keep in mind:

  1. Dosage: It's essential to dose Flourish Excel according to the manufacturer's instructions. Overdosing can potentially lead to elevated levels of dissolved organic carbon (DOC) in the water, which may stress shrimp and other aquarium inhabitants.

  2. Sensitivity: While most freshwater shrimp species, such as Cherry Shrimp (Neocaridina spp.) and Amano Shrimp (Caridina multidentata), are relatively tolerant of carbon supplements like Flourish Excel, some sensitive species or individuals may react negatively to sudden changes in water chemistry. It's advisable to observe shrimp behavior closely after initially introducing Flourish Excel and monitor for any signs of stress.

  3. Acclimation: If you're introducing Flourish Excel to a tank with shrimp for the first time, it's a good idea to acclimate the shrimp gradually. Start with a lower dosage and gradually increase it over several days to allow the shrimp to acclimate to the changes in water chemistry.

  4. Observation: Keep a close eye on shrimp behavior, activity levels, and overall health after introducing Flourish Excel to the aquarium. If you notice any unusual behavior, such as increased hiding, reduced feeding, or lethargy, it may indicate that the shrimp are experiencing stress. In such cases, consider reducing the dosage or discontinuing the use of Flourish Excel altogether.

How to Take Care The Shrimps

Taking care of Freshwater aquarium Shrimps (Neocaridina and Caridina) involves providing them with a suitable environment and proper attention to their specific needs. Here are some essential care guidelines:

1. Tank Setup:

  • Shrimp are relatively small and can be kept in tanks as small as 5 gallons (19 liters), but a larger tank allows for more stable water conditions.
  • Provide hiding spots with plants, driftwood, and rocks. Live plants like Java Moss and Java Fern are ideal as they serve as both hiding places and a food source.

2. Water Parameters:

For Neocaridinar (Cherry Shrimps)

  • Temperature: 72-78°F (22-28°C)
  • pH: 6.5-7.5
  • GH (General Hardness): 6-10
  • KH (Carbonate Hardness): 3-10

For Caridina (Taiwan bee, Crystal Shrimps)

  • Temperature: 72-78°F (22-26°C)
  • pH: 6.0-6.5
  • GH (General Hardness): 3-5
  • KH (Carbonate Hardness): 0-10

3. Filtration:

  • Use a sponge filter such as Qanvee filter or a gentle flow filter to avoid strong currents that can stress shrimp.

4. Feeding:

  • Shrimp are omnivores and feed on algae, biofilm, and commercial shrimp pellets.
  • Supplement their diet with blanched vegetables like Mulberry leaves, spinach or zucchini.
  • Offer a varied diet to ensure proper nutrition.

5. Water Changes:

  • Perform regular water changes (10-20% weekly) to maintain water quality.
  • Use dechlorinated water at the same temperature and parameters as the tank.

6. Molting:

  • Provide a calcium source, such as our shrimp mineral products or crushed coral, cuttlebone, to support molting.

7. Tank Mates:

  • Shrimp are generally peaceful but can be preyed upon by larger fish.
  • Suitable tank mates include small, non-aggressive fish like guppies or endlers.
  • Avoid aggressive or predatory species.

8. Breeding:

  • Shrimp breed readily in captivity.
  • Provide moss or other dense plant growth for shrimp to hide their eggs.
  • Maintain stable water conditions to encourage breeding.

9. Health and Observation:

  • Regularly observe your Shrimp for signs of stress, illness, or abnormal behavior.
  • Quarantine new arrivals to prevent introducing diseases.

10. Patience:

  • Shrimp keeping can be rewarding but requires patience. Allow your aquarium to mature and stabilize before adding shrimp.

By following these care guidelines, you can create a thriving environment for your Shrimp and enjoy their vibrant colors and fascinating behavior in your aquarium.

How to Acclimate New Shrimps & Fish

Acclimating new aquarium shrimp/fish is crucial to ensure a smooth transition and minimize stress. Follow these steps for proper acclimation:

Materials Needed:

  • A container or bucket.
  • An airline tube or a slow-drip system (optional).
  • A net.


  1. Turn Off Lights: Dim the aquarium lights or turn them off completely to reduce stress on the shrimp/fish.
  2. Float the Bag: Place the sealed bag containing the shrimp on the surface of the aquarium water. This allows the water inside the bag to gradually adjust to the tank temperature.
  3. Drip Acclimation (Optional): If you have an airline tube or a slow-drip system, set it up to provide a gentle flow of water from the tank into the bag. This method is slower but provides a more gradual transition. Adjust the flow rate to about 2-4 drops per second.
  4. Monitor Temperature: Ensure the water temperature inside the bag matches the tank temperature after about 15-20 minutes. This step is essential to prevent temperature shock.
  5. Open Bag and Add Tank Water: Carefully open the bag without allowing shrimp to escape. Using a net or your hand, gently transfer the shrimp into a clean container or bucket. Be cautious not to introduce water from the bag into the container.
  6. Gradual Water Exchange: Over the course of about 30 minutes to an hour, gradually add small amounts of aquarium water to the container with the shrimp/fish. This helps the shrimp adjust to the tank's water parameters.
  7. Net Transfer: After acclimation, use a net to transfer the shrimp from the container into the main aquarium. Avoid adding any water from the acclimation container into the tank.
  8. Dispose of Bag Water: Safely dispose of the water from the bag. Do not release it into your aquarium, as it may contain contaminants or pathogens.
  9. Observe and Monitor: Keep an eye on the newly introduced shrimp/fish for the next few hours to ensure they adapt well to their new environment. Monitor their behavior and look for any signs of stress or illness.

Proper acclimation helps reduce the risk of shock and ensures a smoother transition for your new aquarium creatures. It's an essential step in ensuring their health and well-being in your tank.
