Hi Guys, I am sorry to revive this old forum thread, but while searching for solutions to what we are experiencing on the southern end of Lake Huron in Ontario I found this thread and a few others that are describing things that we are just now experiencing. We have some microbiologists looking into this, but this is going to take a lot of time to study. It sounds like you guys have already experienced this, and I wonder if you have any tips, knowledge to share, or maybe an explanation of what this is? It looks like green slime on the line, it starts to bunch up as you bring the line in, and eventually it locks up, and you can no longer reel line in. If you let the line dry out... even for 30 minutes it becomes easier to remove and if you let it dry out completely it turns yellowish green and can be removed for the most part with ease, but some bunches that "turned to cement" need to be broken up before they can be removed. We are also experiencing a lot of line abrasion... I think this is due to cleaning the line off constantly? I have set up extra rods, so I can swap out the dirty rods every 30 mins and put clean ones down, then I wait 20 minutes, clean the dirty ones off and swap again... man it's tedious! Any help, advice, insight as to what this is would be appreciated.
