Product Overview
API's E-Z Pool is a proven choice for homeowners looking to consolidate their weekly maintenance into a single, pre-measured application.
This 5 lbs. container of E-Z Pool Concentrated Pool Blend simplifies maintenance by combining an oxidizer, algaecide, and clarifier into one formula.
