So I'm going to be purchasing a second filter to put on my 125 gallon aquarium ( 2 oscars, 1 jack dempsy, 1 green terror, 2 parrots) and wanted to get some input on what filter I should be looking at, and more importantly the most important features I should be checking out so I can make my own informed decision. I already have an Eheim Ultra G160-2075 Pro, and have been reading a lot of threads and specs on filters, but to be honest I feel like I'm misunderstanding what to look for. For example, I see people comparing an Eheim 2217 as an equivalent to a Fluval 406, but when looking at a spec like the GPH, the fluval blows the eheim outta the water. Also, would it make sense to make the second filter just a mechanical filtration system, or is it still a good idea to keep bio media in there aswell?
Anyway, any help on making my decision would be awesome.
Cheers!
