The Flipper Magnet has become a household name for their popular Flipper aquarium glass cleaner magnets and recently we learned about a new product they are releasing next month and called the DeepSee. Similar to the IVS Portal, the DeepSee will magnify objects between 3″ and 8″ away from the aquarium glass however there are some differences between the two products. The IVS Portal is both a magnifier and glass cleaner for light duty cleaning. The Portal works with glass and acrylic thicknesses up to 1/2″ but it is really not designed to remove stubborn algae and coralline algae when it begins to grow on the glass. The DeepSee magnifier is not an aquarium glass cleaner but it will hold on to glass thicknesses up to 5/8″ MORE
