🔋 Tetra Whisper Bio-Bag Replacement Cartridge Large 12 Pack - Unassembled Review

Easy to use, ideal for filtering a 40 gallon turtle tank, they are unassembled, they require assembly. Which is very easy to assemble, easy to clean.

Perfect filters for my whisper filter. I've been using them for many years. It comes with carbon filters and a net holder. I add my own charcoal ammonia removal stones which I always back order from Revain because they are cheaper than the pet store.

Terrible, just opened the packaging, the plastic was already broken. It comes in parts. You have to adjust your filter all the time. Who wants to spend time doing that?! It's so dumb for 3 packs. I'm so angry I've never hated something as simple as an aquarium filter so much.

Many filters listed. It's actually one filter at a time. So what if you have more than one filter/canister? You must *save the old plastic from another filter. This is not specified in more detail. So with this kit you can save some cash and still enjoy your habit of having clean aquariums.

I've been using my Whisper Biofilter for years now and these packs are great for it. Can be washed and reused a few times before replacement is required. I can dump the old charcoal and just put some fresh charcoal (from a spare canister) in the old filter and let it work. After a few times I put in fresh filters. The filters are very durable and filter out the "health" in the water very well.

Don't forget to hold the blue cap, there is only one and it must be reused. Don't forget to put the blue clip in your pocket before putting the charcoal in. Suitable for normal freshwater aquarium. I use this particular filter for 10 to 20 gallon Tetra Whisper Internal Filter, Aquarium, Air Pump Tank Filtration (Model Number: 25817 ASIN: B0002DHYG8). I gave this one star for easy cleaning because I don't think you'd want to try to reuse a bag/bag. And here's the blue bracket, it can be washed…
