Perfect fit
They fit amazing it’s very hard to find these in Particular and easy to take out to clean tank.

They Need A Little More "Backbone"
We're wintering over 7 good sized goldfish from an outdoor fountain tub in a 20 gallon tank using an Emperor 400 type E cartridge filter system rated for an 80 gallon tank. The Marineland filters are a little pricey so I thought I'd try a dozen of these and see how they work out. The price was good, the purchase was easy, the delivery prompt and they appear to be doing the job. My disappointment is that the 'cartridges' have a little too much flex in them so I needed to use the Emperor charcoal containers as a back up to hold them in place. I'll likely purchase them again but I was asked for a review so .....

Good quality filter
I had bought a cheaper filter from a online pet store which fell apart in the 50 gallon tank and we are still trying to get the pieces out. These filters are good quality and they are cleaning up the mess. I would definitely buy these over and over.

Good availability of hard to find parts find
Great! I have an older tank with weirdly shaped filters,v and no other place has then in stock anymore... But you had them! Thanks!

Just What I Needed!
I was frustrated having to 'build-my-own' filter cartridge each time and decided to try these. they fit perfectly, saving me time and headache! They arrived quickly and I will certainly order them again.
