Coral Seas Yellow Out – 2 lb by Coral Seas

Yellow Out is a chemical breakthrough! Amazing cleanup results when used prior to an EPA-Registered chlorine that kills, green, yellow, pink and brown algae.

Yellow Out is not an algaecide, herbicide or pesticide. It does not contain quatemaries (foam), copper (stain), silver or poison. Yellow Out will not kill algae. However when Yellow Out is used with EPA registered chlorine, cleanup is achieved quickly and economically.

Please Note: Never mix Yellow Out and EPA registered chlorine or any other chemicals together in a bucket and always rinse the bucket out after each use.
