People who keep turtles are often faced with the issue of contamination in their aqua-terrarium, including problems such as cloudy water and accumulation of sludge on the substrate. Tetra ReptoClean contains highly active enzymes and bacterial concentrates, which decontaminate the water and accelerate the decomposition of organic material, such as uneaten food, excrement and dead plant material..This creates a clean and healthy habitat for all creatures living in the aqua-terrarium.
