Effective and affordable.
I love these filters. They work perfectly for my 5 and 10 gallon fish tanks. The filters are have a slim design and easily slide into my water filtration system. I just remove the old filter and soak a new one in the tank until it is completely saturated. Then simply slide into your filter. They are that easy to use. No mess to clean up. The filters are very quiet and I have mine in the filtration system for about a month. If for some reason the filter needs changing before that I can hear the water running through the filter and I know it’s time to replace it. These are very durable and dependable filters. I’ve had problems ordering from other companies that change designs without advance warning. I really love my fish and want to provide the best possible high quality environment for them. These filters have consistently been the same every time I order them and they arrive quickly. I think they are extremely affordable and do excellent in a heated tank. I have fresh water tanks that stay around 78 degrees. These work very well and keep everything clean.

Works for the Price Point
We have two fish in our tank and these keep it clean for about 1.5-2 weeks before needing to clean the tank. I have noticed that when we only have one fish, it’s usually closer to 2 weeks before we need to clean. But the package comes with 3 filters, and does a decent job. I think part of it is more the filter itself than these cartridges. Happy with the product though.
