I have a "My Reef Creations" FMC-422 and need replacement filters. I reached out to MRC and they forwarded my e-mail to a dealer who was kind enough to offer me two filters for "$34.99 plus shipping". If I have to bite the bullet and buy them from that dealer fine, but that's highway robbery. It's literally $2 worth of some sort of washable filter media that is about 1" thick and cut into a 4" circle with a hole punched out of the middle. I'm a little miffed by the price. Does anyone know of any alternative sources for that type of filter material?
