Waste of money

Had the filter for 6 months and stopped working. Multi-filter just costs three times more for three separate filters, then stops working.

No, I do not recommend this product.

Great Replacement

Linnea2

Even better than the old one, that failed after 30 years; right fit for a special upright tank; easy setup. Glad they stuck to original design: if it ain't broke, don't fix it.

No, I do not recommend this product.

Terrible - does not self-prime

Bayobio

Broke after less than a week. Does not self prime if power outage occurs? Came home to a burned out motor and could not get it to restart despite researching online and finding it is a common issue. Will not buy another Fluval filter!

No, I do not recommend this product.
