Hey all, if anyone is considering purchasing a Whisper Internal power filter made by Tetra here's a little bit of info I got today.
Story first:
I bought two of these, same model-----the 20i rated for 20 gallons for added filtration to go with my HOBs. The one I bought at my LFS had a foam cartridge (for biological filtration) that goes in front of the carbon cartridge, but the one I bought at Wal-Mart didn't. I looked high and low for this extra foam cartridge------I couldn't find it anyhere------not even Tetra's website. I called Tetra and they are sending me one free. They told me that from now on the new Whisper internals would all have the foam cartridges in the box, I guess it's an upgrade.
Moral of the story:
If you buy one of these filters (they work good as an add-on, not sure about main filtration), look for a black foam cartridge in a plastic clip. If you ain't got one, just call Tetra at 1-800-423-6458 and they will send you one. This extra foam is important for biological filtration, because the carbon cartridge will get tossed out in 4 weeks resulting in bacterial loss and possible mini-cycle. :eek:
P/S: Thought it was mighty kind of Tetra to send me one for free!!! I was looking to purchase. I knew there was a reason I use a lot of their stuff!!!
