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

A clean fish tank is healthy for the fish.

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.

Things You'll Need

• Algae scraper/pad
• Water siphon
• Bucket
• Vinegar
• Filter brush or tooth brush

Instructions

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.

Tips & Warnings

• Scrape the tank's glass weekly. Clean the filter and gravel monthly. Wash your hands after each tank cleaning.
