Fluval U3 Underwater Filter Foam Pad

i highly reccomend this product. Easy to install and very easy to change out. I only use this filter media for my under water filter.

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

I replace this once every other month and it does a great job of keeping my red-eared slider's water clean and clear, along with weekly partial water changes.
