Terminalia catappa L.
General information
This plant grows in nearly all tropical areas around the world. The tree is salt-tolerant and therefore cultivated as a sun shade on beaches. Its area of natural growth spreads from Madagascar to India and as far as the Fiji-, Ryukyu- and Bonin-islands.
Effect
The agents in the leaves (et al. tanning agents) have a mildly desinfectant and fungicide effect.
Therefore, this plant can also be used preventatively e.g. against fungi growing on the spawn, but also for the treatment and phrophylaxis of finrot and mucosa problems.
The pH-value only drops unsignificantly, the overall salinity (guide value) only increases marginally.
Within a short time, the water becomes amber-coloured, but remains crystal-clear.
Dosage
Use 2 - 3 leaves for 100 l water.
Simply place a leave on the water surface. After 1 - 2 days, the leaves are soaked with water and sink. Apart from their positive effect, they are also a vision of delight in a semi-natural tank.
After 2 - 3 weeks their effectivity fades and they may be exchanged.
