Simply Betta Crystal Clear

Cloudy water is most often caused by tiny particles suspended in the water. Because these particles are too small and light to be trapped by a filter or to sink to the bottom of the tank, they remain suspended. Using a few drops of Crystal Clear will attract the tiny particles that cloud up your tank water, making them larger and heavier so that they sink to the bottom or get trapped in the filter. Crystal Clear is non-toxic and safe for fish and plants. Treats 20 gallons. 3/4 ounce (22 ml) per bottle.
