Not a design template Creates a crystal-clear tropical water environment and has an algae-preventing effect. Promotes the health of fish through humic substances from peat and tannins from oak bark. Promotes spawning readiness through active iodine. Makes it easier for all blackwater fish to get used to it (e.g. neon, angelfish, discus, etc.). Has a stress-reducing effect. Don't worry - your aquarium water will not turn black or Braun when using JBL Tropol! The humic substances it contains only give the water a color that is barely visible to the human eye, but which is excellent at preventing algae growth. Only in the event of a severe overdose can a clear brown coloring of the water be seen with the naked eye.
