I don't think the color of the water is related to the filter, I think that you water is turning brown and have organisms growing in it because of the wood you have. "Driftwood" releases tannings for months, so that explains the color (if you recently added the wood) and the organisms are mosquito larvae (I think). I have seen them growing when I neglect to change the water in which I'm soaking pieces of driftwood. And the only thing I can say about the output is that when you compare the output of a power filter to that of a canister, the power filter seems more potent. I hope that helps.
