I think you really should look into getting a grid based aeration system. Those pictures are telling me high nutrients, nothing in the pond to utilize them, so that grows a bunch of phytoplankton. With a high fish density, you might experience a summerkill. Dying the pond will cut back on phytoplankton, but what is in there to produce O2? Nighttime is the most crucial time for low O2 events.
