How To Apply

This product comes in easy to use water-soluble packets and can be used in ponds, fountains, bubblers, and disappearing waterfall features. Simply toss the packets into your water feature and let your pond do the rest. For best results apply packets into the filter if possible or apply directly to the pond in an area of the greatest circulation.
