This cleaner works well with my FX6 filter. I run it weekly and notice the gravel stays much cleaner. No need to manually clean the substrate, which saves time and effort.

Easy to set up and integrates smoothly with my existing filter. The automatic function keeps the bottom of the tank clean without disturbing the fish. Slight improvement in water clarity after a few weeks.

Works as expected, but I found it takes a few minutes to start cleaning. Not a major issue, but it’s worth noting for first-time users.
