I have a 1.5 acre pond that is feed by a 180' deep well 1.5 hp pump that flows about 30-40gpm it comes in on one end of the pond at about water level. The pond looks very clean and fish are very healthy but I would like to get more circulation as the water seems really warm on the top and is probably not near the bottom. I just finally got the well pump replaced yesterday and am topping off the pond the about 2-3 feet it was low. It was filled a couple months ago just from rain but this will keep it full all the time and keep fresh water coming in. Anyway to my question do you think if I make the 2 inch line taper down or add a valve to up the pressure or add a spray bar etc I can get the circulation of the water up without adding aerators? Have any of you done this or maybe added a line to make a large sprayer?

Thanks in advance
