green algea in dugout

[danny W1M]

Green algea in dugout showing up in my spray supply dugout water. Usually through in a pond dye before it gets started, somehow forgot this year. What can I use, now that it's already in the dugout. I think pond dye stops it from starting but won't control it once it gets going. Have a bit of spraying yet to do, but also want good water for the fall.

Can I use bleach, if so, how long before I'd be able to spray from it?

I couldn't see anything in the SK spray book this year, did I happen to miss the info?

Blue stone (coppersulphate) will get rid of it coop should have it or a feed mill.

aqua mark.blue dye is for sure the way to go.but should be used before growth starts.

Bluestone is the way to go will be clear in a day.
