JBL Aquaristik und Terraristik Tropol, 100 ml, D

Reduces stress, creates a crystal-clear tropical water environment, and prevents algae growth. Promotes fish health through humic substances from peat and tannins from oak bark. Supports breeding readiness with active iodine and facilitates the acclimatization of all blackwater fish (e.g., neon tetras, angelfish, discus, etc.). Tropical water conditioner. No worries - your aquarium water will not turn black or brown when using JBL Tropol! The humic substances contained only give the water a color that is barely visible to the human eye, yet effectively prevents algae growth. Only in cases of severe overdosing will a noticeable brown coloration of the water be visible to the naked eye.
