Magnum 350
Well, I was planning on getting 1 XP3. Well, my local pet store is selling used Magnum 350's for $20. I'm not sure if these canister filters provide biological filtration. On Marineland.com they say that the filter's output can be connected to a Bio-Wheel PRO 60. Well, does this mean that the water will be falling like a waterfall. I don't want that to happen, I want it so that both hoses stick right in the water. Will I be able to do this? Do I need the Bio-Wheel PRO 60 attachment to recieve biological filtration or will the Magnum 350 canister filter has a place to put the media? On the website it says not all Magnum 350's come with Carbon/Media Container and Water Polishing Micron Cartridge. Does this mean in the Media Container I can put biological filtration media. What the heck is biological filtration media, is it just carbon? If so, how often do I replace the carbon?
