2 Barrel Pond cleaning system DETAILED STEP BY STEP

I made this DIY 55 Gallon 2 Barrel Filter POND FILTRATION SYSTEM for my Outdoor kio pond.
I looked on the internet for a filtering system and could not find anything with good details so I made this. This is my first Instructable, I'm not an expert and this pond filter experiment has been pulled together from other Instructables and internet research.
