What customers say
Customers overwhelmingly praise METALfree for its exceptional reliability in managing pool metal content. The product excels at sequestering iron and copper, effectively preventing unsightly stains and scaling, especially after adding fresh well water. Reviewers appreciate its dual strength in both preventative maintenance and active stain removal, noting visible improvements quickly. It is considered gentle on pool surfaces compared to harsher options. While highly effective, the primary concern noted is the premium price point, which some users find significant for larger pools. Overall, users justify the cost through superior performance and ease of use in maintaining water clarity.
