This thing is pretty simple which is what makes it work so well. Not to say there are not improvements to be made... I'm already working on version 1.3.
The "big gee-whiz" of this thing is the round handle which makes it easy to spin the tool and the algae collection end is splayed out to hook the string algae.
Insert tool in the pond and let it rest on the algae. Spin the tool and the algae wraps around the PVC pipe. Remove the tool from the pond and slide the algae off the end of the pipe... sorry, you have to use your hand.
All I can tell you is it works pretty well as a first pass to remove the large masses of algae. Chemicals are needed for the cleanup and if I owned one a pond vacuum would be nice.
When you own a pond algae will always be present. One of the key's to having an attractive pond is clear water, some plants, waterfalls and no algae. It's the "no algae" part that is unattainable but algae can be managed.
To manage algae all you need is lots of time, a few coins, lots of time, patience, lots of time, more patience, chemicals, patience, additonal patience.....
It's too bad Billy Mays isn't with us anymore as I would have him selling these by the thousands! Sure...
