I still use an under gravel filter and it's getting harder to find parts, but these still work great and I'm glad PetGuys still carry them!

It's very hard to find these filters for my old but functional tank and filter system. So glad you still carry them. Great service, low price and fast delivery.

Great Price... Product received as ordered... Received delivery in like 3 days, well before the "5 to 7 business days..".. Thank-you for restoring faith in my fellow man...!! Refreshing to get really good service, instead of the modern day "don't give a #$@%" service... Thank-you..!

Under gravel filters

I purchased the FC-4 filters in hopes that they would fit any of the lift tubes I currently own but is was not to be they are too small. The good news is a customer service rep said he could order me the correct ones from Penn Plax. Thanks for going above and beyond you have a customer for life.
  • The Con is perhaps adding dimensions could have prevented a return. I am sure the filters do the job in the proper lift tube.
