How to Clean a Tank After a Fish Died From a Disease

A fish which lacks proper care can develop diseases and soon die; this leaves the water infected and results in a diseased fish tank. Cleaning a tank in which a fish has died can be time consuming; it must be sterile before more fish are added. Cleaning the tank after the death of a fish is a relatively simple process if you are equipped with the necessary items. A diseased fish tank needs to be thoroughly cleaned in a particular order.

Instructions

  1. Clean Inside the Glass

    • 1

      Clean the inside of the glass. Use an algae scraper or scrubber pad to remove the dirt and debris that may have accumulated. Move the scraper in either a circular motion or up and down. The inside glass must be cleaned first as it allows residue to fall into the tank's gravel.

    • 2
      Plants, rocks and decorations should be removed prior to cleaning.

      Remove any plants or decorations. Set them aside in a separate bucket. Use the algae scraper to clean the plants and decorations.

    • 3

      Vacuum the gravel. Use a water siphon to remove any dirt or debris.

    • 4

      Clean the outside glass of the fish tank with vinegar and water. Do not use commercial glass cleaners as they contain ingredients harmful to fish.

    • 5

      Replace the decorations and plants in the tank. Position them as desired.

    • 6

      Rinse the filters with water. Use a filter brush or a toothbrush to reach into the crevices to clean the dirt.

    • 7

      Replace the water that was taken out of the tank while vacuuming. Refill the tank with fresh water.
