One of the most common problems you will run into when storing rainwater is the algae growth in water tanks.
Here we are going to show you three simple tips for how to eliminate algae growth in water tanks.

ONE: Always use a completely opaque water storage tank – Algae uses photosynthesis to reproduce – in simple terms, algae needs light to grow. So, if your water tank does not allow light in through the roof or side walls, algae cannot grow.
TWO: Add a quarter teaspoon of bleach to every gallon of water you store – Bleach kills algae and prevents it from growing. A common question is: will plain old household bleach remove algae from water? Household bleach will work fine for this.
Pro tip: We suggest you use bleach that is five point two five percent hypochlorite. Do not add both bleach and chlorine to your water. Use one or the other
THREE: Add four parts chlorine to every one million parts water – Chlorine also stops algae growth. In this small of a ratio, the water will still be safe to drink or irrigate with. The most important thing to remember is to follow the ratios of bleach and chlorine very closely.
Too much of these elements in your water can be harmful
There is no point collecting rainwater if it is only going to be ruined by algae growth. So, keep your water clean and usable with these three tips.
