I used the "Carefree" system from my Beachcomber dealer. Very simple to use. Only 2 products. One about 15mins before you get in and another once a week. Change water every 4 months. It was so good that I quit testing the water and just relied on the additives.....
Pretty sure it's a different Groundhog that's shut down for logging. Can't see the one at Wells being shut down....but I don't know for sure. I just remember seeing a different thread talking about areas shut down for logging and Ground Hog was one. But it's somewhere else in the province...
We just came back from a week of riding in the area. No mud, lots of forestry roads. Awesome scenery! Favorite rides were Small River and Horsey Creek. Good rides for all skill levels. I would like to explore more closer to McBride. Holmes, Renshaw etc. You won't be disappointed.
