With Tropol, JBL specifically developed a water conditioner for blackwater aquariums. It creates a characteristically tropical environment with crystal-clear water. Algae are largely denied essential light radiation, because Tropol has a light filter effect, comparable to sunglasses. Humic substances of peat and oak bark tannins promote the health of fish. Furthermore, the settling-in phase of the new arrivals will be facilitated significantly through its stress-reducing effect. Tropol is recommended for every water change, as well. Additionally, the readiness of Blackwater fish like tetra, barbel, discus, neons and angelfish to spawn gets increased by active-iodine, additionally.
