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

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.
