As individuals..we all must conduct our lake usage accordingly.  We share this beautiful setting ..collectively.   So….ANTIFREEZE story

Our boats will be going in soon.    Some are just “drain” like one of mine.  Others, including PWC’s hold antifreeze over the winter.   It would be optimal if you flushed that before launching.   With my PWC….I simply blast it on land for a few seconds.. to  blow antifreeze out.

The more expensive stuff like propylene  glycol antifreeze is used to reduce aquatic threats.  It is blue, pink, or clear and less toxic than other antifreeze

Lets say 50 boats are put in with antifreeze.  ..so 50 x 1.5L is 75 liters or about 20 gallons.   I purify lake water ..anything that is foreign to water displaces oxygen.
