Tetra Blackwater Extract 100ml

Tetra Blackwater Extract

Recreates the blackwater conditions found in many tropical streams and rivers

• Easy and quick to use - 6 readings in 60 seconds
• Improves spawning success, health, and colouration in many species of aquarium fish
• Aids plant growth with selected minerals and trace elements
• Limits the growth of bacteria and fungi
• Helps to control algae, by reducing the penetration of light into the aquarium

Application - Add 5ml of Blackwater Extract per 10litres (2 gallons) of aquarium water initially, followed by 2.5ml per 10litres (2 gallons) every 1-2 weeks, as part of your normal maintenance schedule. Blackwater Extract may initially turn the aquarium water a slight brown colour, until the ingredients have fully dissipated. Activated carbon and other chemical filter media may remove Blackwater Extract, and so should be removed during its use.
