AMTRA Oak Extract

Echein Extract from Amtra is a natural product made from crushed oak bark that can lower the pH level sustainably to very low values.
Unlike Catappa leaves, oak extract practically does not color the water in your aquarium.
The 150ml bottle can treat approximately 3000 liters.

AMTRA Oak extract advantages:
• Oak extract is mainly used to maintain fish from black and/or acidic water biotopes in optimal conditions.
• Oak bark extract creates suitable living conditions for freshwater fish from tropical regions.
• Acts against the dark coloration of Discus
• Stabilizes the pH sustainably at very low values, in combination with Amtra Trop.

10 ml can treat approximately 200 liters of water (depending on the starting pH)

We recommend preparing the water in a container so as not to change the aquarium water parameters too quickly.
It is recommended to lower the pH of your aquarium, by unit of 0.5 / day.
