PondCare Accu Clear is a colorless liquid that rapidly eliminates cloudy water in koi ponds and water gardens. Newly constructed ponds may develop cloudy water during the first few weeks, especially in warm, sunny conditions. Established ponds can also experience cloudy water any time. Cloudy, discolored water may form while changing the filter, working with aquatic plants or when making a water change. In all these instances, Accu Clear quickly restores pond water to a crystal clear condition. Accu Clear causes tiny, suspended cloud forming particles to clump together into larger clumps called flocs. Once clumped together these flocculated particles are easier to trap in the pond filter than the tiny particles, thereby aiding the filter system in keeping the water clear. If the pond does not have a filtration system, the flocs will settle to the bottom of the pond or become trapped in the pump prefilter. As the water clears, the particles will accumulate in the filter and it will be necessary to rinse the prefilter and filter pads/foams more often when using Accu Clear to regain crystal clear water. Directions for Use Mix the desired dose with one gallon of pond water and distribute evenly around the perimeter of the pond. Add 1 teaspoonful 5 ml for every 50 U.S. gallons 190 L of pond water. Water will clear within several hours. If a second dose is necessary, wait 24 hours before applying. Filter pads should be rinsed frequently when clearing pond water. Accu Clear can be used once a week to keep filters performing at maximum efficiency. Accu Clear can be used in ponds and water gardens containing koi, goldfish, and aquatic plants. Overdosing with Accu Clear causes the product to work more slowly. Compatibility Before using Accu Clear, make certain that the pond has vigorous aeration, a fountain, waterfall or aeration device especially durin.
