Review on Aqua Flo 12-Inch Pond & Aquarium Filter Media, 6-Foot Long x 1-Inch Thick (Pink/White) by Satsuki Silva

I really like this filter mat on my 150 reef tank. It's finer mesh than the regular blue we're used to, done, but when you have an algal bloom like mine, it clogs quickly. No problem with the pillow, shall we say. I recommend it for a well-functioning system, but you may want to use cheaper materials if you have a lot of algae or very dirty water. In general it works great, you just want more for the money.
