Requirements for Keeping Floating Aquarium Plants

Lighting

  • Choose a light source that produces the right wavelength of light or spectrum to promote photosynthesis.
  • Avoid fluorescent lights, which are too intense for some plants.
  • Look for a light source between full-spectrum and actinic blue.

pH Value

  • Monitor the tank’s pH regularly.
  • Fluctuations in acidity can lead to problems such as stunting plant growth or even death.

Substrate

  • The substrate should be between 2-5 cm thick.
  • It should have good drainage.
  • Popular substrates include sand, gravel, clay pellets or specialized plant-specific types such as aqua soil.

Aeration

  • Aeration ensures sufficient levels of dissolved oxygen are necessary for healthy photosynthesis.
  • Without adequate aeration, aquatic organisms may suffer from hypoxia leading to reduced growth rates and higher mortality rates among species like fish and invertebrates.
  • Use a power filter, air pump or bubbler system to maintain optimal conditions.
