Dock Disk for Zebra Mussels

[HalfmoonHoobler]

Has anyone used the Dock Disk (https://www.thedockdisk.com/) at their slip to keep Zebra Mussels away? Does it work? Is there risk of galvanic corrosion? (I believe it releases copper in order to keep the zebra mussels away). I haven’t used it yet - but just looking for advice on its effectiveness and if it’ll harm my boat. Any help you can provide would be amazing - thank you!

good question. I found it here: https://www.dailytrib.com/2020/05/20/marble-falls-experiments-with-zebra-mussel-repellents/

This paragraph in the article: At the Lakeside Park beach, the city plans to install Dock Disks along the concrete wall and buoys to discourage mussels from taking hold there. Dock Disks are a brand of 7½-inch foam disks that emit a 7- to 8-foot radius of zebra mussel repellent, which is copper-based. The repellent isn’t harmful to people or fish as used at this level.
