12. Do the nutrition capsules dissolve in water?

Nutrition Capsules do not fully decompose and the small balls inside the capsules will remain in the substrate after all nutrients have been released. The balls are made of resin, which is biologically harmless. They do not alter the parameters of the aquarium. 

13. How to use nutrition capsules?

Nutrition Capsules is an extra nutrient supplement – use tweezers to place the capsule in the gravel, close to the roots of fast-growing plants.  

Nutrition Capsules contain both nitrogen, phosphor, iron and micronutrients. The nutrients are slowly released as the plants need them over a period of 1-2 months. Use Nutrition Capsules for stem plants, Cryptocoryne, Echinodorus, Vallisneria etc. – all plants with sturdy roots. 

14. What ppm do I dose to my tank if I add 2ml of tropica specialized nutrition to my 50l aquarium?

You can see the conversion will equal 2.000 ppm: ml/litre = 1 x (1000x0. 001) ml/litre =1000(0.001ml/litre) =1000ppm. Try Tropica’s APP for all the guides and help you need and receive 90 days help alert for free.

15. Does Tropica Aquarium Soil have an expire date?

There is no expiration date on Tropica aquarium Soil or Soil Powder. In the aquarium, the Soil can typically last a few years without losing effectiveness. However, individual experiences may vary depending on conditions.

16. I have done standard checks like light, nutrition, water quality, but my plants are still not growing well

If you've already checked the light, nutrition, and water quality in your aquarium but your plants are still not growing well, there could be a few other factors to consider:

  1. CO2 Levels: Adequate carbon dioxide (CO2) is essential for plant growth. Insufficient CO2 can limit plant growth, causing them to appear stunted or discolored. Consider adding a CO2 system.
  2. Substrate: The type and depth of substrate can impact plant growth. Some plants require nutrient-rich substrates. Ensure that your substrate provides the necessary nutrients and supports root development.
  3. Water Circulation: Poor water circulation can lead to stagnant areas where nutrients may not reach the plants efficiently. Consider adjusting your filter setup or adding additional circulation pumps to improve water flow throughout the aquarium.
  4. Pruning and Maintenance: Regular pruning and maintenance are essential for promoting healthy plant growth. Remove any dead or decaying plant matter, as they can contribute to nutrient imbalances and algae growth.
  5. Plant Selection: Some plant species may not thrive in your aquarium conditions, such as lighting intensity or water parameters. Consider selecting plant species that are better suited to your specific setup.
  6. Algae Competition: Algae can outcompete plants for nutrients and light, inhibiting their growth. Implement proper algae control measures, such as regular water changes, maintaining nutrient balance, and optimizing lighting duration and intensity.
  7. Pests and Diseases: Check for signs of pests or diseases that may be affecting your plants, such as yellowing leaves, holes, or unusual growth patterns. Treat any issues promptly to prevent further damage.


17. Should I use tap water or reverse osmosis water?

Whether you should use tap water or reverse osmosis (RO) water in your aquarium depends on various factors, including the specific requirements of your aquarium inhabitants and the quality of your tap water.

  1. Tap Water: Tap water often contains chlorine, chloramines, heavy metals, and other substances that may be harmful to aquarium fish and plants. However, in some cases, tap water might be suitable for certain hardy species or if it's treated properly with a water conditioner to remove harmful chemicals. Tap water also contains minerals that can be beneficial for aquarium plants.
  2. Reverse Osmosis (RO) Water: RO water is purified through a filtration process that removes most impurities, including chlorine, chloramines, heavy metals, and dissolved solids. It provides a blank canvas for aquarium keepers to control water parameters precisely, making it ideal for sensitive fish species, breeding projects, or planted tanks with specific requirements. However, RO water lacks essential minerals, so it may need to be remineralized before use in the aquarium.

Ultimately, the decision between tap water and RO water depends on your aquarium setup, the species you're keeping, and your willingness to adjust water parameters. You may also consider using a blend of both tap water and RO water to achieve desired water parameters while still benefiting from some of the minerals present in tap water. Testing your water parameters and understanding the needs of your aquarium inhabitants will help you determine the most suitable water source for your setup.
