Fluval U3 Underwater Filter Poly/Carbon

Replace these filters for my two tanks.

IS WHAT IT IS

Maintains my crystal clear 55 gallon tank.

I use this foam pad obviously in a fluval 3 filter. The filter is amazing, I have a turtle tank and it keeps the water crystal clean. Easy to clean and easy to replace dirty pads and such. Great product

These are kinda hard to find so i have these saved and Ive bought a few times for my turtle tank. They are exactly what I need for her filter.

Work great, like advertise. I just wish there was a better indicator when to change the filters.

Best way to buy these supplies!

Water flow is great again. Thanks for the new filter. I tried cleaning the old filter several times but still doesnt work good.

monthly aquarium maintenance

Keeping the tank clean good product
