I added the Fluval Moss Ball to my 10-gallon tank with dwarf shrimp and small tetras. The water clarity has improved noticeably over the past two weeks. The moss looks natural and doesn’t interfere with the fish behavior. I don’t have to clean the tank as often now.

It’s a simple addition that works well in my freshwater setup. The moss stays intact and helps keep the water clean. I noticed less algae growth after introducing it. A good decorative piece too.

My shrimp are more active and the water looks clearer. The moss ball absorbs nitrates and phosphates effectively. It’s easy to place and doesn’t float away. I’m happy with the performance.
