The sponge fits perfectly in my Betta filter. I’ve used it for two months now and the water flow is steady. I cleaned it with old tank water as recommended and didn’t notice any loss of bacteria. Easy to replace and holds up well.

Works well with my Betta filter. I noticed a slight improvement in water clarity after replacing the sponge. I followed the cleaning instructions carefully and haven’t had any issues so far.

Great product. The sponge is soft and doesn’t damage the filter housing. I’ve used it twice now and it still performs well. The instructions were clear and I followed them exactly.
