  1. Drain the Aquarium: If there is any water remaining in the aquarium, drain it completely. You can use a siphon hose or a clean bucket to remove the water.

  2. Remove Decorations: Take out any decorations, such as rocks, plants, or driftwood, from the aquarium. Rinse them thoroughly under running water to remove any debris or algae.

  3. Scrub the Glass: Dip the soft-bristled brush or algae scrubber into the algaecide solution and gently scrub the interior glass surfaces of the aquarium. Pay special attention to areas where algae or residue may be stubbornly attached. Avoid using abrasive materials that could scratch the glass.

  4. Clean Decorations: If the decorations are heavily soiled or covered in algae, you can soak them in the algaecide solution for a few minutes to loosen the debris. Then, scrub them with a brush or algae scrubber to remove any remaining residue. Rinse the decorations thoroughly under running water to remove the algaecide solution.

  5. Rinse the Aquarium: Once you've finished scrubbing the glass and decorations, rinse the aquarium thoroughly with clean water to remove any traces of the algaecide solution. Make sure to rinse multiple times to ensure all residues are removed.

  6. Inspect for Residue: After rinsing, inspect the aquarium for any remaining algae or residues. If necessary, repeat the cleaning process in areas where algae or residue persists.

  7. Dry the Aquarium: Allow the aquarium and decorations to air dry completely before refilling it with water. This will help ensure that no moisture remains, which could promote the growth of algae or other unwanted organisms.
