Top Fin Silenstream Large PF-L Filter Cartridges Refill for PF30, PF40, and PF75 Power Filters - 6.5in x 4.5in Review

Matches our filtration system for our fish tank. The convenience of having them on my doorstep is why we bought them. We will order again.

As described. This is the filter cartridge I needed. The filter doesn't seem to pump the volume it's supposed to (the next size up filter should have been bought), but it's a filter, not cartridges.

They proved to be more expensive but of higher quality than the model they replaced. They worked great in our 75 gallon filter. And because they're pre-assembled and feature dual charcoal chambers, they're less messy and more powerful.

I had to buy them from Amazon because Petsmart was out of stock. They seem to have virtually no carbon in them, so they don't work as well as the ones in Petsmart. They are also double the price of Revain, very disappointed in them.

This product is not what it says it is. It doesn't fit in my filter box, even though the box says it fits 20s. I am very disappointed and am trying to get my money back. I don't think this is a true top fin product. The packaging and labeling has been slightly altered so it's easy to miss when ordering. Big mistake!

I have a 33 gallon tank with two filters. I changed the water, washed and installed the new filters. An hour later, the aquarium slowly began to turn green. The next day the water was green with algae and my fish were dying. I did a complete water change again, cleaned everything, threw out the filters and first emptied the pool without a filter. The water was clear for a week. I put in two more filters and an hour later the tank turned green again. So upset!

I had an emergency and waited too long to go to PetSmart to replace the PF-L filters. My fish may have died and I may have an electrical overflow problem. I used it to replace the filter in my 29 gallon tank. The PetSmart had a generic filter media that I had to redesign to make it work, but it held me back. Thanks for the filters. They were 1 day late but I think it was due to a payment issue.
