How to Remove Algae From a Turtle

Most wild turtles have some algae growing on their shells, but in a well lighted home aquarium, pet turtles can accumulate a lot. Algae is unsightly, and can potentially mask shell problems, so it's a good idea to keep it under control. Inspect your turtle's shell closely at least once a week to make sure problems aren't developing underneath the coat of algae. This also gives you a good opportunity to clean the shell.

Instructions

    • 1

      Scrub the turtle's shell with a soft brush or sponge to remove algae and slimy film. On smaller turtles, use a toothbrush. On larger turtles, a soft sponge can be used on large areas and a toothbrush on crevices.

      Make sure the turtle has a spot where it can climb completely out of the water to dry out. Drying out will kill algae and bacteria on the shell.

    • 3

      Remove the turtle from the aquarium for a few days and keep it in a dry plastic container with a pan of water that is too shallow to dive in. This will also dry out the algae and kill it.
