All of our aquatic botanicals are intended for ornamental aquarium or terrarium use only. Please use common sense and take the time to boil and/or soak and thoroughly rinse botanicals prior to using them, to reduce the possibility of problems. An additional several days submerged in freshwater with a bag of activated carbon is strongly advised. Always go slow when introducing any botanicals into your systems, so you can judge the effect they have on your fishes and plants. They are not intended for human consumption. DO NOT INGEST!
Tannins don't just discolor the water. They also tend to bind up minerals in the water, softening it and lowering the pH, hardness and alkalinity. All aquarium fish have ideal ranges in terms of pH.
