I am thinking about buying a small Shop Vac to help clean my pond. Is there
a model that will blow out the water rather than holding it in the tank?
That way I will not have to empty it every few minutes.

Also, what is the best product to clean green water? I have been using
AlgaeFix from Pond Care and it seems to be clearing it a little, but it is
still very green.

Thanks for any help.
