The Juwel Biocarb sponge significantly improved water clarity in my 20-gallon tank. After a week of use, the water became noticeably clearer and the fish seemed more active. No fish were affected, and the odour reduced quickly. Easy to install and maintain.

I used this sponge to address a persistent smell in my aquarium. It worked well and helped reduce cloudiness. I plan to use it monthly during water changes. The small size fits perfectly in my filter housing.

Great product for maintaining clean water. After installing the sponge, my tank water stayed clear for over two weeks without any noticeable odour. It’s a simple and effective solution for daily aquarium maintenance.
