فلاتر الحطام البديلة - الإسفنجة السوداء

These are exactly the same size and density as the originals that came with the fountain, so they fit snugly without any gaps. I've washed the first one three times now and it's still holding its shape, which makes the ten-pack feel like it'll last a long time.

Ten sponges for this price is a steal, and they fit my fountain's filter slot exactly like the originals. I rinse one every few days and swap in a fresh one, so having a whole pack means I'm not stuck scrubbing the same sponge forever.

I bought a pack of these black sponges as spares and they fit the fountain perfectly. It's nice that they're washable, though I wish the pack had a few more for the price. Still, they do the job well and keep the fountain clean.
