Superfish Algenschuim

I’ve had this sponge for a few months now, and it still wipes off green algae in one easy pass without leaving a single scratch. It even handles that stubborn limescale ring near the waterline without any extra scrubbing. Exactly what I needed for my tank.

I was skeptical a soft sponge could tackle the crusty limescale on my tank, but this one wipes it away without scratching the glass at all. Takes me about five minutes to do the whole front pane, and my fish don't even notice I'm cleaning.

Finally, a sponge that scrubs clean without scratching the glass. I used it on a stubborn limescale ring left from evaporation, and it dissolved away with almost no effort. The soft texture is exactly what my acrylic tank needed.
