Bioclean is a natural aquarium cleaner that combines 2 products; bio digest and bioptim.
Bioptim also facilitates the elimination of nitrates and phosphates, which are an early warning sign of algae problems, and carbohydrates, and therefore helps to regulate decomposition odors and optimize water quality.
Dose your tank every 15 days. One standard vial treats 30-50g. One Pro vials treat 250-500g. Prodibio doesn't spoil, and you can't overdose it.
