When we purchased our 23.5 in 1993, folks around Lake Erie were trying to figure out how to deal with the invasive species, Zeebra Muscles. We contacted the Ohio Sea Grant, an envirionmental group that's associated with Ohio State Univ. and several other universities and government agencies, because we, at the time, were planning on trailering Kinship between Lake Erie and several inland lakes in NE Ohio. The recommendation that we got was to add 2 - 4 oz. of househould bleach to the ballast tank to kill any zeebra muscles. They felt that, since chlorine naturally breaks down so quickly, that little, if any would make it into the lake, and there should be little to no environmental impact.
