Preparation and Safety Guidelines

Tools Needed
  • 4mm glass panels
  • 3mm ventilation mesh
  • 5mm base glass
  • curved glass profile
  • PVC rails
  • metal ruler
  • measuring tape
  • knife
  • stainless steel mesh
  • 180 & 400 grit sandpaper
  • silicone sealant
  • masking tape
  • acetone
  • scraper
  • shear
  • finishing tool
  • two liter water bottle
  • 10x10cm PVC profile

Safety Guidelines
  • Always ensure your aquarium is securely placed on a stable, level surface capable of supporting its weight when filled with water. Avoid placing it near heat sources or direct sunlight.
  • Never use tap water directly in your aquarium. Use dechlorinated water (e.g., aged tap water or bottled spring water) to avoid harming your fish. Always test your water parameters before adding fish.
  • Thoroughly research the specific needs of any fish or plant species you intend to keep before purchasing them. Incorrect water conditions, temperature, or tank mates can be fatal.

Tips

  • Use masking tape to avoid silicone overflow.
  • Think upstream about which surfaces will receive silicone.
  • Use weights to maintain pressure while silicone dries.
  • Pre-drill holes for screws to prevent glass cracking.
  • Use a scraper with a new blade to remove excess silicone.

Common Mistakes to Avoid

1. Incorrect Substrate Choice

Reason: Using the wrong type of substrate can lead to nutrient imbalances, affecting plant growth and water parameters. Poor substrate choices might also not provide enough stability for planted aquascapes.
Solution: Select a nutrient-rich substrate specifically designed for planted aquariums, such as a mix of soil and aquarium-safe gravel.

2. Overstocking the Tank

Reason: Overstocking leads to excessive waste production, ammonia build-up, and poor water quality, harming fish and plants. It can also disrupt the aesthetic balance of the aquascape.
Solution: Research the appropriate stocking levels for your chosen fish and plant species, ensuring sufficient space and filtration for all inhabitants.

FAQs

What kind of plants are best for a European-style Asterion aquarium?
Low-growing, carpeting plants like Hemianthus callitrichoides ('HC Cuba') or Glossostigma elatinoides are ideal for the densely planted look of a European-style Asterion tank. Adding taller stem plants in the background for contrast also works well. Avoid overly large or fast-growing plants that could quickly overtake the scape.
How often should I perform water changes in my Asterion aquarium?
Regular water changes are crucial for maintaining water quality. Aim for 25-50% water changes weekly, depending on your tank size and stocking. More frequent smaller changes are generally preferred over less frequent larger ones.
