The blue coarse sponge fits perfectly in my Aquatop CF-500UV. It captures large debris well and keeps the water clear. Easy to clean and lasts longer than the original one I had.

Works great with my reef tank. The flow remains steady and it helps reduce visible particles. I’ve used it for two months now and it’s still performing well.

Fits exactly as described. The sponge holds up well during regular cleaning and doesn’t break easily. I noticed a noticeable improvement in water clarity after installing it.
