Review on Fluval Universal Media Filter Pack by Laura Washington

I used a bag of Fluval charcoal to store charcoal in my 38 gallon mini reef aquarium and replaced the charcoal sponges that came with Innovative Marine with a small bag of charcoal. The pouches are made of a comfortable material with a fine mesh that allows the liquid to flow while the medium is inside. There is an "inverted trident" clip which is very easy to use and secures the media pouch by preventing the contents from falling out. I was impressed with the design and ease of use. The bag is large enough to hold a significant amount of media, although I only filled it about 15-20% full for my use. I am glad that I bought this product.
