Works good. Smells like rotten eggs.

So, I guess the rotten egg smell is the bacteria. Thankfully, it only smells for a little while. It does a good job keeping our pond clear. We like it. Would have given it a 5 star if it didn't smell.

We use it in our fish holding tanks at our store and in our small ponds. Works great!
