Tetra 25994 Bio Foam Grid Replacement Kit with Whisper 30/40/60 Power Filter

Works fine as expected

It's nice to be able to purchase these separately without buying a complete back filter. They work very well used in conjunction with charcoal filled filters. I've noticed that my freshwater tank looks much clearer since I've started using them. They are awesome in my marine tank, as well.

My old one wore out, so I searched for a new one. Yes it's a bit pricey but it's exact. The picture looks like you get 2, but you only get 1. They do not sell just the foam, wish they did. This way I just pull the dirty one out and put in the cleaned one without turning off the pump.

These screens work great and capture a lot of gunk making it easy to clean the filter each week

Some of the elements I've used in the past were too thin. This one is thick and dense enough to give good filtration.

There ok I thought it was a pair but was only one... ended up being too small for my system!

Hadn't bought a replacement in awhile. These are great, easy to clean.

Like others reported only one item shipped and will not fit my AquaTech Filter for Aquariums, 20-40 way too small. tried to do a return got put in an endless circle no way to return for a refund ! Not happy I have always had good experience with Amazon issues :(
