I have a koi pond. And a pool. This Skimmie is one of the best accessories I have for my pond and pool. The pond has a skimmer just like a pool. I use the skimmies hook to pull the cover of the skimmer off. Pull the basket out to clean when necessary, use the net to do a quick cleaning of the basket. The fine mess net is perfect to grab uneaten food, pine needles, and all the gross stuff you don't want to touch. The hook works great to pull out the filter pads. This item belongs on shark tank. Amazing. ALL POND OWNERS... THIS IS A MUST HAVE.
