Fluval carbon great, cust. Service awful by Fishiefriends05/20/2013
Ordered these carbon packs for my aquarium as I was due for a change. They were listed as in stock, 2 days later I was told they were out of stock, 2 weeks later still had heard nothing and tried to get a hold of cust support regarding the issue, about a week after that they came.

I have two zoomed filters designed for turtle tanks (I forget what they are called), and after a few months of them getting way too dirty I read a review on amazon that said to use these filter cartridges instead since they let water pass through them much better, and they were 100% right.
