2. Remove used cartridge from bio-holster by pushing down gently on the holster and pulling the tab on the filter cartridge upwards. Discard used filter cartridge. Bio-holster should not be removed or cleaned, as it contains living bacteria.

great value


Best value I could find online! Fast shipping and the product arrived well packaged, and exactly as expected. Website is easy to navigate and use, as well. Thanks!

Aqueon Filter Cartridge


Much better deal here than buying at the pet store. Website is easy to navigate through; shopping and checkout was a breeze. They also offer an email alert when this product goes on sale! Shipping was quick, on time and very well packaged. These filters work well, last about a month and have never given me any problems. Excellent product!!!

Aqueon filters


Would rather buy from here then at pet store. Much cheaper and shipped really quick. Thanks.

Aqueon filters


I can't believe the difference in price from a regular pet shop. You save at least half the amount! I am very impressed with That Fish Place with their price,service and shipping.This is the place I will go for any of my aquarium needs!!

Great filters


The best prices on replacement media I have found! Thank you!
<br>I use 2 of the large filters on my 125 gallon Oscar tank and it keeps the water crystal clear.
<br>The media is super easy to change and they clean easy too, so I can reuse them a couple times.

They do their job


These filters catch a lot of debris. Yes, you may change them slightly more often, but they are doing a better job cleaning the water. The tank is cleaner and the fish are less stressed. If you are in the market for a new aquarium filtration system, I would recommend these filters.

Filter pads


There are the best pads I ever used and any of my fishtanks they're high-quality low-cost just a great all-around for any type of fish pads for aquariums .your long-lasting if you take proper maintenance with them.keep up the quality

$31.99 is JUST TOO MUCH.....


These are GREAT. My issue is the cost $ 32.00 for only 12, That's only 6 wks worth here at our house. Even with rinsing them out to get just a few more days out of 1 set . you should offer a volume discount. People who buy this have a large tank, ours is 80 gal. The investment has already been made. You need to help us continue to enjoy our tank, so we will be back for our "Care needs". We will have to look else where, like Amazon to cut this price to maybe $24.99. I would spend $100.00 to get 48 wks of "Care Free Fish Lovin"

Cost of large cartridges


The cartridges cost are way out of line.I don't know if its the manufacturer or you all.This product used to be 19.95 a bvox of large!!. So lets get with the program.
