ScumBall

It does what it says it does. It collects all the sunscreen oils that otherwise build up on the walls of your pool or in the skimmer basket. I have used this product for one season and can't see any reason it won't work for a few more. These clean up really well with some dish soap. Just make sure you rinse it all out well before throwing this back in your pool.

Just what we had expected. Delivery was within expectation.

Received the scum balls just before a large group hit the pool for a 4th of July party. Picked up a lot of scum that would have gone to more expensive and difficult to clean filters.

The product usually comes in a two pack which is what I thought I was getting for the price charged. You'll pay less for two at your local pool supply store.
