Good morning. Great information above. Here is a link to a surface
skimmer that I use.

Depending on what type of filtration you have on your tank, this works very well with hang on back (
HOB) filters. Average cost $8.00 Not only does it skim the surface but adds more oxygen into the tank as well. As Shawnie mentioned, an air supply with air stone will help as well
When you have the chance, if you'd be so kind as to fill out more of your aquarium information it would be a great help and help others to help you more.
Welcome to Fish Lore and enjoy the site.
