How to Remove Bubble Algae

Bubble algae, sometimes referred to as sailor's eye, is a species found in saltwater aquariums and oceans. A bubble alga resembles a light to dark green bubble beneath the water. Its surface is shiny and resembles a sheet of smooth, thin glass. Within each bubble are several algae spores that will produce more bubble algae if they release into the water. Common algae-eating fish will ignore bubble algae, as it is not part of their natural diet. The best way to deal with bubble algae is to remove the growth yourself.

Instructions

    • 1

      Put on a pair of rubber gloves before removing bubble algae. This prevents any of the algae spores from getting into minor cuts or abrasions on your skin, should a bubble rupture.

    • 2

      Use the tip of a sharp pocketknife to dislodge the area of rock, coral or sand to which the bubble algae is attached. Be careful not to slice into the bubble, as you will release spores into the water and propagate more bubble algae. It might take a high amount of pressure to dislodge certain surfaces.

    • 3

      Scoop the dislodged bubble from the tank, using the ladle. Do not attempt to grab it with your fingers, as you risk rupturing the bubble and releasing the spores.

      Repeat the process with any remaining bubble algae. Remove the bubble algae one at a time to avoid rupturing any while you work. If a bubble ruptures, you will notice new bubble algae growth over the next few weeks.
