I ordered the stuff and I found that it was a waste of $$$. What I ended up
doing to remove the leaves and muck at the bottom was to purchase the
aqua-gloves that go to your elbows and using a net scoop out the leaves. I
also use a Craftsman Wet/Dry shop vac to get the rest of the stuff out. Once
your pond it clear of the debris you can add you pond start bateria (make
sure your water temp will keep the bacteria alive) then its business as
usual.
