Review on Marina Filter Ceramic Cartridge 9 Count by Erika Howard

I can tell you the 10 and 20 gallon Marina filters are excellent and so are their filters. I've been using Marina for about 5 years. Better than Tidal 35 and Penguin Biowheels. Pretty, easy to use and the price won't send you to the poorhouse. I use two 20's and one 10 gallon. performance filter. I would have shown you a video of them in action but I wasn't around when I wrote this review. ⭐⭐⭐⭐⭐👍
