I need some help in understanding my koi. I have a 7,000 gal pond about 2 month old with about 30 kois 16" to 28". Pond doing great and bottom algae growing out very fast. About a week ago my koi started eating all the bottom algae up at a very fast rate, now they are starting eating them of the walls. I know it's not harmful to them, but it's killing my skimmer with left over algae and I'm cleaning out my skimmer filter everyday. I have also increased my koi feeding to 4 to 5 times a day. Anyone have any ideas please let me know?
