Title: Crap.
Review: Has caused me nothing but trouble and the loss of a fish. I bought this filter for a 30 gallon gold fish tank, as what I thought would be an upgrade. With-in a month both of my large gold fish had ick, which eventually killed one of them. Since then I test my water very frequently and have found that even with a 50 percent water change I can not keep the nitrates at a safe level.The manufacture suggested that I change the filter media once a week, and do a 50 percent water change at the same time.I do not have the time or money for this filter. Will not be purchasing another Marineland product.
