Question 1

does anyone have the exact measurements for the X large + Medium filters?  Thanks

Accepted Answer

Must be a secret - I sure don't understand why the seller doesn't clearly list the size.Whisper Bio-Bag Filters are slightly tapered in the drawing. Width dimensions are at the top.Large: 4.6 wide x 6.4 tallMedium/"Junior":  3.0 wide x 5.2 tallSmall: 2.1 wide x 3.8 tallFound dimensions on the Tetra website but not sure the link address will work here. Here is the PDF file link:http://cdn.spectrumbrands.com/~/media/UPG/Tetra/Aquarium/Equipment/Replacement%20Filter%20Cartridges/WhisperCartridges.ashxIf this doesn't work go to their website at: www.tetra-fish.com and search for "Tetra Whisper Unassembled Bio-Bag Filter Cartridges"

Question 2

Does it fit topfin power filter 10?

Accepted Answer

I bought these about a month ago for my top fin 10 filter.  The cartridge in my top fin 10 is angled inward at the bottom whereas this filter cartridge is more of a rectangular shape.  Due to the shape it does not fit the top fin 10 slot.  However I kept my old cartridge frame and I'm using this product, everything works great.

Question 3

What is the difference between the 26164 and  ATS26164? Both seem to be 12 large Whisper filter cartridges.

Accepted Answer

Hi, I use the Medium size whisper filter cartridges...the difference between the 26164 & ATS26164 could be the fact that one is a pre-assembled cartridge and the other is not.  I buy the 12 pack of unassembled filters which are quite a bit cheaper and are the identical product.  It comes with the white filters, one plastic insert, and small charcoal bags that take a few minutes to assemble.  Hope this helps.
