Bioactive Tapsafe is a unique and advanced formulation developed in conjunction with global leaders in Biotechnology. It removes chlorine, chloramines and heavy metals and this in turn allows even hot tap water to be used as part of a water change mix. An Aloe Vera protective colloid within Bioactive Tapsafe creates a barrier around the fish's delicate skin and gill membranes. As an added feature it also adds a culture of bacteria and enzymes that consume any excess biological waste in the aquarium and boosts filter performance.
