WTB Biogrid for Whisper 30-60 filter - Jasper, TN

I need at least one biogrid, with or without the foam, that will fit a Whisper 30-60 filter. It's an older filter that someone gave me and after cleaning it up, it seems to work well. I just need the cartridge/grid that holds foam.

It wouldn't hurt my feelings if anyone had one to give away for just the cost of shipping

Or at a reasonable price.

Thanks for looking.

Hi. I think what I was given is an older model but the ones you have are the newer type and looks like the same thing. The measurements are close. Mine is technically 6 15/16" x 3.5" - 4" (bottom is narrow than top).

The ones you show look just like the ones on Tetra's website. Does your say a model number inside the grid or a model number? The specs are so close that I would say it will fit my Whisper 30-60.

Here is what mine looks like. I haven't cleaned it yet, it's the way I got it

I tossed all of mine. I just get media inserts from kens fish. They are like $1.05 each. Just slide them in.

Yes, this filter uses those too. But the grid holds a piece of foam that you don't ever throw away or either not after several months. Just a rinse out in tank water and you put it back in. It's not the same as the cotton and carbon filters that you throw away every month (or sooner).

Well these are plastic-no numbers on them but they came out of a whisper 40 and they.re also for the whisper 60. I still use both of those filters but not the grids. If you want them you can have them (free)....as many as you want. Just pay the shipping and there yours.

Thank you. But you're the second person so far saying you don't use them

May I ask why? Are they not the 'bio component of the filter? Do the filters work better without them?
