I have a rain barrel as well and use the water for my garden. It was well worth the investment as I'm on city water and there are times when we are restricted on water use due to drought. This alleviates the need in many cases. I use mosquito rings in the water every year - one generally lasts for six months, so they are fairly cost effective. While I wouldn't drink the water, it's certainly safe for other purposes and is does not get icky.
