I really like these, they help keep the water clean.

Worked well

As advertised

It was as advertised

Would buy again

These work well to replace the OEM filters that came with my Betta fish tank. No complaints, perfect fit, water stays clean. The tank I have requires 2 so this will only last 3 months for me rather than the 6 months that is advertised. Not really an issue though. Happy so far with these filters.

Have purchased multiple times for my daughters fish tank. They work great and good value to compare the pet stores.

Very effective filter cartridges.

Found it to be essential for a clean and healthy tank.

It works!
