i have use them in my reefs tanks for yeas , i am a believer of them
 
Its like 12-15 dollars...

I was just wondering if this is a good investment for fresh water tank
 
Don't use them, the risk is much higher then the supposed benefits.

Edit: Now that I've posted this, I gotta find the site I'm basing this off, and google is being a pain. Give me a few.
