Week Aqua substrate for aquascape – stable parameters and long-lasting nutrition

Week Aqua Substrate is a specialized soil primer created for planted aquariums and aquascaping, where the right substrate determines long-term success. It combines a nutrient substrate and an active primer, providing constant access to macro- and microelements, while stabilizing pH and supporting the development of beneficial bacteria.

What makes Week Aqua a reliable choice

• Ideal granule size 1-4 mm, ideal for aquascaping.
  
• Provides a natural and stable environment for plants from the start.
  
• Maintains a slightly acidic water environment - ideal for most aquarium plants and shrimp.
  
• Contains a rich mineral profile for long-term root nutrition.
  
• Optimizes oxygen circulation in the substrate thanks to its porous structure.
  
• Does not require washing and is easy to place, making it easier for beginners.
  

Technical benefits for aquascaping

• Stimulates rapid rooting and adaptation of newly planted plants.
  
• Reduces the risk of fluctuations in water parameters at start-up.
  
• Suitable for nano aquariums and large systems.
  
• The color emphasizes the green tone of the vegetation and improves visual depth.
  

Determine the layer thickness

• Nano aquariums (up to 40 l): 2–3 cm is sufficient for stable rooting.
  
• Medium aquariums (40–120 l): 4–5 cm guarantees optimal nutrient reserves.
  
• Large aquariums (120+ l): 5–7 cm for long-term stability and growth.
  

Adjust the selection to the type of plant

• Low and medium-demanding species → standard thickness.
  
• Plants with a powerful root system (Cryptocoryne, Echinodorus) → thicker layer or additional tablets.
  
• Appropriate layout according to the aquascape
  
• Foreground → thinner layer for a clean visual profile.
  
• Background → thicker layer, supporting tall species and stability when pruning.
  

Frequently Asked Questions (FAQ)

1.Does it need to be washed before use?

No. The substrate is placed directly to preserve the nutrient layer.

2.Is it suitable for shrimp?

Yes, the active primer maintains the pH within optimal limits for Caridina and Neocaridina.

3.What is the durability of the nutritional properties?

On average 12–18 months, depending on the load and maintenance.

4.Can it be combined with inert sand?

Yes, but it works best as a basic substrate layer.

5.Does it affect the initial start-up of the aquarium?

Yes - it helps to establish biofiltration faster and reduces stress for the plants.

Week Aqua substrate offers a balanced combination of nutritional value and control over water parameters - a key factor for a successful planted aquarium. Whether you are starting a Nano system or creating a complex aquascape, this nutrient substrate and active primer provides you with a solid foundation for long-term growth and visual aesthetics.
