Great filter

I love these. They are used for my Slider Turtle's fish tank. My sweet Pebbles needed a filter that really worked. I buy a large amount because they are inexpensive

I love these. They are used for my Slider Turtle's fish tank. My sweet Pebbles needed a filter that really worked. I buy a large amount because they are inexpensive. And you get 3 in a pack. They absorb completely. So happy with this product!

How come three not four?

How come the package only contains three filters instead of four? The filter requires four filters but the package only contains three. Also why don’t you carry

How come the package only contains three filters instead of four? The filter requires four filters but the package only contains three. Also why don’t you carry the bio-clear filters? We have only goldfish. Can’t seem to be able to purchase those filters anywhere. I know that the packaging isn’t your fault. But so far the filter is working great.

I like this filter & cartridges. There isn't space for a filter pillow and I'm adding a pillow for water harness. So I'm adding a second small filter and a stronger pump to handle both filters. But that's okay. They each have their function. 20 gallon tank.

I have had so many different aquarium filters over the years, and this cartridge and filter are great. For small aquariums, it keeps the water clear. It is also very easy to change the filter. Everything works really well and it is quiet because the pump is located in the water. Very pleased with this product.

Nice filters

I appreciate that these filters have both zeolite and carbon. The filter media is fine; therefore, it catches more debris than other filters.
