Hi, I'm new here.
I live in michigan and have a 1/3 acre pond. I have largemouth bass, hybrid bluegills and channnel catfish.
I also have an areator.
I have been battling Chara for years without much success. I use powerderd copper sulphate, copper sulphate crystals and cutrine plus.
The FA is taken care of but the Chara is heavy.I try to mechanically rake it our every year but I'm getting up in years and it's exhausting. My first two years I tried Karmex and it did a wonderful job but reading the label scared me and I have not used it since.
The Cutrine plus label says you have to wait till the water temp reaches 60 F before application. But the darn Chara grows all winter (in Michigan!). So either way If I kill it or not I still have to rake it. Also the level of my pond fluctuates about 3 feet from spring to fall. So When I used the karmex I got a ugly mud bad around the pond in the fall. I'm wondering if Hydrothol would work better than the cutrine plus. Or if there is a better method. HELP !!
