## Description

Fluval U2 Underwater Filter Foam Pad

Review: Impressed with Results - I’ve been using the Fluval U2 Chemical Filter Cartridges for a few weeks now, and the difference in tank cleanliness is night and day. These cartridges do a fantastic job keeping my water clean and clear. The dual-sided design is especially effective—one side traps fine particles like debris and uneaten food, while the carbon side removes odors and discoloration. Within just a day or two of use, I noticed a significant improvement in water clarity and smell. I use them in a freshwater setup, but it’s great to know they’re also safe for saltwater and reptile tanks. Plus, installation in my Fluval U2 filter was quick and easy. If you’re looking for an efficient, no-fuss solution to maintaining a spotless tank, I highly recommend these cartridges. My fish seem happier, and I’m spending less time on water changes and tank maintenance!
Review: Especially useful following water change - When the tank is all stirred up following a water change, I slip these in my filter to grab the big stuff before putting in a regular filter with charcoal. It helps grab the big chunks and plant material. I always have one of these and a charcoal filter working together, and it really helps. I have three goldfish fish in a small tank, the bio-load is pretty constant.
