I purchased these filters for ease of use, because I need someone to watch my fish while I'm away. Just pitch it and install the new one. The only reason I only rated this filter bag a 4 is if you don't mind taking a few minutes to pour in the charcoal and rinse, the box of 12 un assembled filters are about the same price as these 4. These ones are custom cut to better fit my filter 'holder', but the un assembled ones are more squared off at the bottom. They don't fit quite perfectly, yet they still work just fine.

How can a filter get a 1 in there rating, I use these filters all the time and they are great, I have never had a problem and trust me I have a 75 gallon tank and some big fish NO HUGE fish all 3 of them. I have an under gravel filter along with Whisper ex 70 top filter along with a an Aqua Clear filter. So For my money you can't go wrong with these filters...THEY ARE FINE !!!!!!

I have a 55 gal tank. I change 1/3 of the water once a month. My filter takes two filters. At the pet shop they are expensive. By shoping at Amazon I was able to save enough to pay shipping and still beat the pet shop price. Same filter, same package.

I use these for my 2 goldzilla fish. I had the fish for 4 years now. This is the first time carnival fish survived in my house. I learned a lot over the years about goldfish care. I had to upgrade the tank 3 times and we are at 40 gal right now (20 gal. per goldfish is the rule). Upgrade the filter 2 times because before I thought bigger filter would mean less cleaning...wrong.... bigger tank means less cleaning. So I've had this filter over 2 years. I take it apart completely and clean it with pressure water only, every 3 months instead of once a week now with the bigger tank. I change these filter cartridges once a month, and I this is better price than wal-mart. So I buy here, but wow I was changing these cartridges, at least rinsing them off once a week until I got a bigger tank. My filter works better, my tank stays cleaner now, and the cartridges work just fine and this is the best deal I've found for them.

You can never go wrong when you buy the large 4pack. This keeps me good on these filters for 6 months because I don't change but one side of the filter every 6 weeks. This is because I want the keep my nitrogen cycle established when I swap them out. I know it takes 6 weeks for the cycle to establish, that is why I do it every 6 weeks. These companies just want to make money when they say replace sooner.

As for the carbon, YES, it does make the water beautifully clear but it is not needed more than every 6 weeks, and we know the established nitrogen cycle is more important than clear water. If you don't already you should operate at least one more sponge filter in combination to the EX 75.

I recently started a fish tank for my kids with the help of a neighbor who is an avid fish keeper. The Tetra Whisper EX 30 was his recommendation, and I couldn't be more happy with the filter. I let the tank go for about 1 month before doing my first filter change. What I pulled out looked nasty, but clearly did the job a filter is supposed to do. And changing the filter is literally a snap. Pull out the filter holder, remove the old filter, and snap a new one in place. I don't think Tetra could make it any easier. Great filter and very easy to use!

I recently got my old fish tank out of storage and found that my old power filter stopped working. I purchased a new Tetra filter which uses these cartridges and am very happy with it. The worst part about the old filters was having to take them apart to get the plastic frame out and re-use it with the new filter. This style eliminates all that extra handling and mess! Simply open the hinged external frame to dump the old cartridge in the garbage, then put a new cartridge in the frame. Couldn't be simpler. Wish they came up with this 15 years ago!

I would have given this the five starts the only reason I didn't is the item does not come with the timer strips. The little black thing you would push down and it would time release something to let you know when the change the filter. With my busy life style it was really nice to have. But the item is cheaper then at any pet store so I will stick with it. Not that much of a issue.

Other then that item did as should and is just as good as the one you buy from the store only with out that timer strip.

I opened the (sealed) box and only got 3 filters. First page of reviews and somebody else had the same problem, so this is probably pretty common.
I'm sure Amazon would refund no problems, but I also realized I ordered a size too big - so rather than deal with all the hassle I just made them fit, dealing with it for now.

But again - check your box as soon as they are shipped. Don't wait until it is too late!
