Sarah Knox –
The filter pads work well with my FX5. I noticed a cleaner flow and fewer particles in the water after installing them. The biological filtration has improved noticeably over the past few weeks.
Leonard Sutherland –
I’ve used these pads for about a month now. They catch small debris that the foam stage misses. My tank looks clearer and the water quality feels more stable.
Diana Cameron –
Great fit for my FX6. The pads hold up well and the bacteria colonization is visible after a few days. I didn’t have to replace them early, which is a relief.
