OK here is the plan for water change, I think?

I need to clean my filter and clean the bottom of my pond. After many
beers I came up with a plan. I would like to know if this would work
or do I need more beer to come up with another plan.

1.) I plan on filling a laundry bag with my bio material (scrubbies,
hair curlers, bowling balls whatever the dollar store offers). Then I
will weigh it down and sink it to the bottom of my pond for a spell.
Hopefully this will get the bio bugs working in my bio stuff. Then
clean my filter and put the new bio bug filled media in it. and fill
it with old pond water.

2.) Next drain the pond, clean and fill from the hose. Wait 2 days
for the chlorine to dispel. Turn on my pump to start my filter
working with the old pond water in it.

3.) sit back and have a beer.

Does this sound like a feasible plan?
