Has anyone used an algae scrubber on their system. I have been doing a little bit of research and was wondering if they are as good as people are saying. My main concern is does it smell "fishy or seaweedy? I know funny question but my wife has a sensative nose, everytime i clean the tank or do water change she says it smells like the ocean and feels nausious (would you believe shes a Newfie..lol) and gets a little upset. I cant smell anything... I would love to build one to help keep phosphates and such down.
