What are effective ways to prevent algae/mold growth in rain barrels?
Despite the appearance and scent, algae found in rain barrels are typically not harmful and the added nutrients may be beneficial to your soil and plants. However, here are a few options homeowners may use to help prevent algae growth in rain barrels:

• Upcycle rain barrels are made of food-grade HDPE that have natural UV inhibitors that will prevent sunlight from entering the barrel and encouraging algae growth.

• The simplest method is to regularly use and/or drain your barrel. Stagnant water promotes algal growth.

• Algae growth depends on sunlight, so install your rain barrel on the side of your home that receives the least amount of sun.

• In addition to sunlight, algae also needs nutrients to grow so keeping your home’s gutters free of leaves and debris will cut off the nutrient supply to the rain barrel.

• Vinegar or bleach may be used in small amounts to stifle algae growth. Add 1 cup of vinegar to a full rain barrel or add 1/8 tsp of regular, unscented, liquid household bleach for each gallon of water in the rain barrel, stir, and let it stand for a day or two before using the water.

• Clean your rain barrel and attachments once per year with an eco-friendly cleansing agent.
