Tropical Blacklarin is a blackwater conditioner with peat extract. This product is recommended for newly set up blackwater tanks, water changes, quarantine, and convalescence periods. It neutralizes toxic heavy metal salts, protects fish from tap water aggression, and reduces stress.

Peat extract provides humic acids and tannins, making the aquarium environment safer and healthier, particularly for neon tetras, discus, angelfish, and other soft-water species.
