Cecil thanks for the reply. I am not sure the water got to below 60 degrees here where I live.

It appears we have about the same size pond and I treated it with cutrine plus liquid. I applied a full pond dose based on the acre foot of the pond or size which mine is about 5,000 to 6,000 square feet.

Aqua Ace and Aqua deuce are microbes I believe - it was recommended by a local fellow who mostly works on large lakes.

Yes my Chara has surely gotten a big head start - it is out of control lately. Do you use the granules and if so are they effective and what kind? How do you calculate how much to use? Yes I believe you from when I treated in the spring with the cutrine liquid that it may not work it did not seem to work then!

I read up on the carp solution a little on the Texas A&M web site and it sounded really like a problem solver.

Do you know anything about microbes and if they are effective in treating Chara?
