I share the same view with Joseph. Algae grow and multiply in the presence of sunlight. Keep your water tank close to prevent penetration of sunlight. Once sunlight do not reach the content of the tank, algae growth will be eliminate. However , you can try the use of GoodlifeUV technology to ensure supply of potable water for consumption .

If you have an open tank or storage that you can't cover, you can use floating plastic balls that are commercially available for covering reservoirs. They block the sunlight. All of the suggested treatment approaches in this chain miss the point. The idea is to passively prevent algae growth. Also preventing growth is much less expensive than treatment and has fewer complications. Los Angeles did this many years ago when they has a solar catelyzed bromate formation problem in their chlorinated open finished water reservoir. It woks great!
