Recommendations: Store hot water above 140°F (60°C). Maintain circulating hot water above 120°F (49°C). Store and maintain circulating cold water below the growth range most favorable to Legionella (77–113°F, 25–45°C). Note that Legionella may grow at temperatures as low as 68°F (20°C).

The active ingredients of this bleach are 5.25% and the amount required to clean the water tank or wells is 1 ppm (part per million). The use of bleach gives a minor chlorine taste and smell in the water!
To keep your aquarium water crystal clear, do regular water changes, use a good filter, avoid overfeeding, test water parameters, add live plants, vacuum the substrate, and control algae growth.
Add activated carbon media to the filter, whether loose or carbon pads. Adding activated carbon media or activated carbon pads to the filter will help clear the water and adsorb nutrients that feed the bacteria bloom.
Always remove any uneaten food promptly. Perform water changes: The single most important way to avoid algae is to perform regular water changes. Change 10% to 15% of your aquarium water every week to lower nutrients in the water.
The most common method for how to remove bacteria from water is through the use of chlorine; in fact, about 98% of public water systems use some form of chlorine for disinfection. Chlorine is frequently used because it is inexpensive and effective.
Epoxy coating
It provides a hard, protective layer that effectively seals water tank surfaces and offers excellent adhesion to various substrates and can withstand heavy traffic, mechanical stress, etc., making it ideal for underground and overhead water tanks.
Add 1/2 cup of unscented household bleach for each 100 gallons of tank volume (i.e. a 500 gallon tank would need 2 1/2 cups of bleach). Fill the water tank with clean water. Run each faucet in the distribution system until you can smell bleach.
To clean out a water tank, thoroughly flush the tank using a bleach solution made with 1/3 cup Clorox® Disinfecting Bleach per 3 gallons water (a 500ppm bleach solution).
Sodium hypochlorite is the active ingredient in household or chlorine bleach. Bleach is a solution of sodium hypochlorite (NaOCl) and water (see pages 2-5). Add bleach solution to the tank and soak all equipment for at least 1 hour.

It is a well known disinfectant for drinking water with many advantages over chlorination. Worldwide over 900 public water systems are using chlorine dioxide for water disinfection.
Chlorine tablets can be used to sanitize water and at higher doses, disinfect the water tank. They can be used in any water tank used to store water for hand washing. *Not recommended for steel, stainless steel or aluminum tanks. Place tablet or tablets in fresh water holding tank.
UV disinfection is the preferred method - no chemicals, cost effective, easy to maintain, does not change taste or smell, and is extremely effective. The UV dose needed to kill 99.99% of e. coli is approximately 6 mJ/cm2. Most residential UV units provide a UV dose of 30-40 mJ/cm2 - more than enough to kill e.
Water storage tanks should be drained, cleaned and disinfected at least once per year.
Boil your water for 1 minute (at elevations above 6,500 feet, boil for 3 minutes), Disinfect water using chemicals, Use a filter designed to remove bacteria, or.
The solution is simple: do nothing. Don't add a UV sterilizer or do lots of water changes to remove the haziness; this just makes the bacterial bloom last even longer. Instead, wait one to two weeks, and the water will gradually clear up on its own as the bacteria reestablishes itself again.
