I’ve used this sponge for two months now and it’s been very effective at removing algae and limescale without scratching the glass. The two sides work well for different types of buildup. It fits comfortably in my tank and reaches into corners easily. No harsh chemicals, which is a big plus for my fish tank setup.
Audrey May –
The sponge works well for daily cleaning. I noticed less algae buildup after using it regularly. It’s soft on the glass and doesn’t leave any residue. The only thing is it wears down a bit after a few uses, but it’s still effective.
