Rated 5 out of 5 by BigDogShadow Great product
I have been running these my Marineland 350's (6) for quite awhile and they are still going strong and doing a good job. The cartridges are good and are reusable. I clean mine in tank water and drop them back in the filter housing. I use the refillable media cartridge in the second slot on each side for whatever chemicals if needed. http://www.amazon.com/gp/product/B0009YHSE8/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Rated 5 out of 5 by Jessey Awesome filter
I love marineland filters, they're awesome! Just to let all the beginners know. You don't have to listen to what the packaging says to how often you should change it. I've been using the same filter pads for at least 6 months. All you have to do to remedy the clogging is to shake it out in a bucket of TANK water to get all the debris loose, that should handle it so you don't have to use a new one. Because most seasoned aquarist know that when you change a filter pad. It causes a bacterial bloom because you just removed it's natural filtration, there in causes cloudiness. Carbon doesn't go bad or stop working people!

I had issues with Aerobic bacteria in my aquarium. After months of unresolved attempts (per professional suggestions) at resolving the problem, I got rid of the Marineland filter/biowheel system. After performing another partial water change, I replaced it with another brand, after approximately 7-10 days, I had nice crystal clear water. I've been using the same system now for 2 years and couldn't be happier. I'm not allowed to name the other brand, but it's also advertised on this site.
