### ⭐⭐⭐⭐ They are okay
*by A***Y on 19 May 2024*

Fluval is the best you can buy. Bought these to stop the algae growth and reduce cleaning time as it says in the box. I added algae liquid solution and filters did not stop the algae growth. Still have to do the usual weekly clean to get rid of the algae.
