3 Ways To Fix A Smelly Rain Barrel Water

If the water in your rain barrel gets starts to smell (or turns green), you have 3 good options:

Option #1 is to add goldfish! They keep the water very clean by eating the algae that turns it green. Keep in mind… when using goldfish as a temporary way to remove algae, don’t just dump the goldfish in a stream or river — because they’re invasive. Instead, give them to a child with a fish tank, or return them to the store.

Option #2 is to add barley-straw pellets. They will kill algae — but won’t harm plants.

Option #3 is to pour a small amount of vinegar into the water. It should clear it up relatively quickly.

As a bonus… the goldfish and the vinegar options (separately) will also kill mosquito larvae!
