  • OZPOLISH Bio-Cure Standard contains 8 different types of heterotrophic microbes, an organic compound in dry form to start nitrification, and easily dissolving base compound. These microbes work together to biologically degrade the unconsumed food, fish waste and other nitrogenous compounds such as ammonia, nitrite & nitrate. Also effective in a tough habitat like those of turtles. Reduces nitrogenous waste supports extended gaps between water changes.
  • OZPOLISH Bio-Cure Standard also has non-microbial organic compound that helps in earliest control of ammonia in a new tank, thus helps in accelerating the establishment of nitrogen cycle in a newly setup aquarium. For better results, mix it (5mg every 3’*1’*1′ bottom) with bed substrate (gravel, sand or soil in planted/ non-planted tanks) while setting up a new tank. Be aware that the biological method of cleaning water is slower than that of chemical methods.
  • OZPOLISH Bio-Cure Standard helps in keeping the aquarium water clean, healthy and eliminate bad odour. Results after a month of regular weekly treatments. When the colony of these good microbes are established they give tough competition to other nasty pathogen, thus also controlling the cause and spread of diseases among underwater lives. Microbial contents are non-pathogenic, and using it along with any other (Non-OZPOLISH) chemical input or medicine may kill the beneficial micro-flora.
