How to Clean Algae from a Water Tank?

Published in Water Tank Cleaning 2 mins read

To effectively clean and prevent algae growth in a water tank, you need to address both the existing algae and its underlying causes. Here's a comprehensive approach:

Prevention is Key

Before detailing cleaning methods, it’s crucial to understand that prevention is often easier than dealing with an algae bloom. According to the provided reference, the most important aspect of preventing algae is using a completely opaque tank, as algae rely on light to grow.

  • Opaque Water Tank:
    • Algae thrive through photosynthesis, requiring light to grow.
    • Using a completely opaque tank significantly inhibits algae growth.

Cleaning Existing Algae

If algae are already present, you'll need to clean the tank. Here's how:

  1. Drain the Tank: Empty the tank completely to remove as much algae-infested water as possible.
  2. Physical Cleaning:
    • Use a scrub brush and a mild soap or a diluted bleach solution to scrub the interior surfaces of the tank.
    • Pay close attention to corners and crevices where algae tend to accumulate.
    • Rinse the tank thoroughly after cleaning to remove all soap or bleach residue.
  3. Disinfection:
    • After physical cleaning, disinfect the tank to kill any remaining algae spores.
    • Use a chlorine solution for this purpose, as recommended.

Chlorine Treatment

Chlorine is an effective method for both disinfecting and preventing algae growth. According to the reference:

  • Bleach Treatment: For every gallon of water you store, add 1/4 teaspoon of bleach to the tank. This is a preventative measure, but it can also help eliminate existing algae after cleaning.
  • Regular Maintenance: Adding chlorine will help keep your water supply algae-free.
  • Safety: Always follow safety guidelines when using chlorine and ensure the solution is diluted properly.

Summary

Step Action Reason
1. Prevention Use a completely opaque tank. Blocks sunlight, preventing photosynthesis.
2. Drain Empty the water tank. Removes the bulk of the algae and the contaminated water.
3. Scrub Physically scrub the tank with brush and soap or diluted bleach solution. Removes algae that have attached to the tank surfaces.
4. Rinse Rinse thoroughly after scrubbing. Remove soap or bleach residue.
5. Disinfection Add 1/4 teaspoon of bleach per gallon of water. Kills any remaining algae spores and prevents future growth.
6. Maintenance Regularly add chlorine when refilling the tank and maintain an opaque tank. Prevents algae from re-establishing.

By following these steps, you can effectively clean algae from your water tank and prevent future growth. Remember, the correct maintenance will result in algae-free water.
