I believe that necessity is the mother of invention. Well yesterday, I needed a vacuum to clean out my new Nursery pond that was getting an accumulation of uneaten food and plant debries. This little pond is a Walmart Kiddie Pool that has a shower drain near the top with a reducer and 1 1/2 ABS return to the main pond. It is fed with a pump exactly like the one I am using for this Power Vacuum which I have named DrDave's Power Vacuum.
On to the build. First you need a Harbor Freight # 47117 pump and from Home Depot a 20 foot length of 3/4" flex hose made by Beckett (garden pond section). Then you need a 1" PVC coupler, 3/4" PVC 45 degree fitting and a 1/2" PVC thread to slip adapter. See the photos for the assemble. I used a lathe to machine the smaller PVC adapter to allow it to fit into the 45 degree elbow. I did not glue anything. Oh, I almost forgot, you need to steal the small vacuum head from your wifes little vacuum. I just happened to have the perfect size. It slip fits and locks onto the 1" PVC connector.
To use it all you have to do is plug it in and slowly move accross the bottom (don't stir up the muck) and discharge it into a plant that could use the nurishment.
