Bacter Crystal is a substrate additive and at the same time a water conditioner which improves soil condition, water quality, health and growth of the organism and colonizes the filter system with beneficial bacteria. Unlike many other products which contains many species of dormant bacteria that may not get fully activated, Bacter Crystal uses only species which can survive in packaging, storage and be activated fully.
Use in New Planted Aquarium Set Up: Apply Bacter Crystal evenly to the base layer of the tank before filling up with soil. Use 1 bottle for a 90cm aquarium. You can also add 2g of Bacter Crystal per 100L as a strong bio-starter, either into the filter/sump or directly into the water.
Use in Aquarium: Add about 1g to 100-200L of water weekly. Mix well with aquarium/pond water before applying. You will notice that the water will turn cloudy initially but will result in much cleaner and clearer water in a few hours.
Shake Well before Use. Keep Dry for remaining Bottle.
