If you read the label when you get it, it will give you mixing rates. Yes, I'd use a surfactant with Cutrine Plus. Or, just purchase Cutrine Ultra, which already has the surfactant in it.

I wouldn't treat more than 1/4 to 1/3 of the pond at any one time. Wait 4-7 days and treat another area. If there is a lot of algae, killing it all at once might cause a DO crash in the pond.
