Just a note that all those yoy BG babies are not supposed to survive. Most have to be eaten or starve with some survivors growing enough. If that was not the case your pond would be overpopulated very quickly with BG. If you have a green tint to the water then there is enough plankton for the yoy BG for now. It may not be ideal but is likely doing just fine for now. This is especially so if you are supp. feeding.
