Easy Baby

Have to disagree with the other reviewer here ... I purchased a Baby biOrb recently for my new Betta after having my first betta living in an airless bowl for a couple years. I simply got tired of cleaning a stinky bowl every week. As a result I went shoppin for a new tank with a bubbler and filter system and found the Baby biOrb.



While I agree that the maintence costs are significant at $132/ year (if you need to change a filter every 4 weeks) the costs balance with ease of maintenance. Personally my experience with cleaning the Baby biOrb was a snap with the optional suction hose. Took me fifteen minutes to clean the tank drain the grimey water and add new water. Couldn't have been much easier. And I am not sure how anyone could have a problem swapping filter cartriges unless they have motor skills issues.



I also built a noise dampening box for the air pump - my only real complaint is that the "whisper quiet" pump sounds like a mini jackhammer after about five minutes.
