To remove algae from an RV fresh water tank using bleach, follow these steps:
1. Drain the fresh water tank completely.
2. Add a mixture of 1/4 cup of household bleach per 10 gallons of water to the tank.
3. Let the mixture sit in the tank for at least 4 hours.
4. Drain the tank and rinse it thoroughly with clean water.
5. Allow the tank to dry completely before refilling it with fresh water.
When using bleach to clean your RV fresh water tank, be sure to take the following safety precautions:
* Wear gloves and eye protection.
* Work in a well-ventilated area.
* Do not mix bleach with any other cleaning products, especially ammonia, as this can create dangerous fumes.
* If you come into contact with bleach, flush the affected area with water and seek medical attention if necessary.
Note: Bleach can damage the seals in your RV's water system, so it's important to use the correct amount and to rinse the tank thoroughly after cleaning it. If you're not comfortable using bleach, you can also clean your RV fresh water tank using a vinegar and baking soda solution.
