Hi Eric. There shouldn't be any issues with treating your entire pond with Cutrine at this time of year with or without aeration. I back off and only treat 1/3-1/2 of a pond during the summer once the water temps get into the mid 80's or higher. An aeration system may allow you to get away with treating most of the ponds surface for a good part of the year but I would error on the side of caution if you have a heavy algae bloom and/or if we are in the dog days of summer. Always evaluate the specific situation before treating. If you have murky water Im guessing you primarily have a band around the shoreline? I'm just up the road from you in southern Madison county. I checked the water temps this past weekend and we were only in the mid 50's up here which is still a little on the cool side for treatments. This weekend is supposed to be cooler so it may be a couple of weeks yet before you get the full effects of a cutrine treatment. How big is the pond and what is your max and ave depth of the pond? Have you taken a couple of water samples to see if the water clears up in the jar on its own or with the addition of alum yet? Does the water tend to clear up on its own later in the summer?
