Koi pond bottom drain clogged (Unclogging koi pond retro bottom drain)

This video was recorded about 2 months ago, when the temperature was a lot colder. But basically my bottom drain got clogged because of the fish, and my bog filters not being blocked of yet. So in this video my brother and I unclog the bottom drain of our pond.
