Product Description

** NOW AVAILABLE ** Healthy Ponds® Blue Pond Water Colorant and Spray Pattern Indicator Pellets are formulated for ease of use in small ponds and water features, or can be used in a spray tank to avoid overlap and missed areas when spraying turf, grass or garden treatments.

Safe for fish, plants, pets and people, Healthy Ponds colorants contain no sulfates or dispersion aids, and are made from the same certifiable food quality dyes used by famous, name brand candy manufacturers in their brilliantly colored hard-shell candy coatings. Blue pond dye tablets are conveniently dosed for small bodies of water. Simply add the correct number of Healthy Ponds Blue Pond Water Colorant Pellets for your pond size. Within 24 hours the water will take on a beautiful appearance, and help make your Healthy Ponds®AquaSpherePRO® more effective.
