Oxidation is a common complaint among aquarists. Over time, the metal compounds in the aquarium glass (or in its support structures) can form chemical reactions to water. This leads to oxidation, which usually appears in the form of hazy, pale deposits that appear "etched" onto the glass of an aquarium. While it can be difficult to remove oxidation from an aquarium, the task is not impossible.

Difficulty: Moderately Challenging
Instructions

Things You'll Need:

  • Backup aquarium or buckets Siphon or pitcher BioClean water stain remover Rag Water supply Stress Coat water conditioner
  1. Step 1

    Unplug all electronic accessories, then transport the majority of the aquarium's water, followed by all the contents of the tank, into temporary holding tank. This is essential for maintaining the health of your aquarium.

  2. Step 2

    Apply the BioClean to a rag, and rub it in a circular motion along all parts of the aquarium glass. Begin by using broad, sweeping motions, then concentrate on the most severely oxidized parts of the aquarium. Small circles are more effective than up-and-down motions.

  3. Step 3

    Rub the BioClean into the glass until it has air-dried. If there is any excess liquid, wipe it off using a dry towel. Very stubborn oxidation stains may require that you repeat the process several times before the stains are fully eliminated.

  4. Step 4

    Wait at least one hour, then rinse the aquarium glass using a hose or shower head on its highest setting. Every inch of the glass should be rinsed several times before it is safe for housing fish again. It may help to rub the glass with a clean sponge to loosen any remaining BioClean residue.

  5. Step 5

    Replace the water, fish, plants and accessories. Water treatment with Stress-Coat can help to minimize damage and shock to the fish, and can also help to chemically stabilize the water. You may need to remove oxidation from your aquarium as often as twice per year.

Tips & Warnings
  • Test BioClean on an inconspicuous area, such as the bottom of the tank, before using it on large portions of the glass.
  • BioClean is natural and non-toxic, but it should be rinsed from the aquarium glass before the tank is re-stocked.
