Vinyl Fungus (Vinyl Plague)

Vinyl fungus, sometimes referred to as the vinyl plague, is a phenomenon where soil fungus grows through the outside of the liner into the pool. It often appears as a dark stain originating from a central point on the bottom of the liner.

This unique problem for vinyl liners is most prevalent in areas of high water tables. The fungi prefer dark, damp, cool environments – making the bottom side of a liner a perfect habitat.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_column_text]

Vinyl Fungus Recommendation

To truly get rid of the fungus, the liner must be removed and the ground treated with an EPA approved fungicide. However, this can be costly.

Alternatively, there has been varied success keeping the fungus at bay utilizing algaecides. We would recommend first doing a treatment using our strongest algaecide Swamp Treat™. This will kill all the fungus that is visible. One bottle treats 20,000 gallons. Simply follow the directions and super-chlorinate (consider using trichlor chlorine for best results).

Once the visible fungus has subsided, you will need to immediately begin a preventative regiment to keep the fungus from growing. Remember, the fungus is still present under the liner and will continue to attempt to grow into the pool. We recommend using No Mor Problems®. Just squirt a few ounces in every time you add chlorine to your pool to keep the fungus from growing through the liner again.[/vc_column_text][/vc_column][vc_column width=”1/2″]
