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.
Really tried to love this filter. Ended up replacing it

I bought 2 of these slim filters for my childrens' tanks. I bought all the cartridges to go with them. I really tried to love this filter, but have ended up replacing both of them before I even got to use these cartridges! The filter is noisy, gets clogged easily, and ends up with water dribbling down the back. I have been keeping aquariums for 35 years and am well versed in filters. The slim filter is just a bad design and the cartridges get slimy and clogged up very quickly causing the filter to back up.
Great filter cartidges!

These filter cartridges keep my water very clean! I hadn't used a filter before and the water kept getting a film on the top but these have stopped it!

These filters do not filter good at all. After a week they are crap.

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

I was very pleased with the speed and I now no longer have to rely on my grandchildren to shop for me! I am a big girl now (age 74) and ordered these "all by myself"!
Great price, prompt delivery.

I always buy extra filters when I buy a new hang on back for any of my aquarium s. These are real thick and really good quality they fit great inside the unit.
Very easy installation
