ok so Ive been watching the site for a while now, but becouse my computer sucked ars I hadnt done alot of things that I wanted to with it like actually introing myself and joining in on the fun. let me start by saying that this is a great site and Ive already started applying some the stuff Ive learned here, so thanks to everyone who makes this possible. Now for my question, I just moved into my first house with my wife and kids its a rental but its a start. I currently at my moms have a 60 gal tank that I used to growout 2 peackockbass now about 5" each, one tiger oscar hes at about7", a senegal bicher which is around6" two gars one spotted 8" and the other is a more common, I dont know its name but it maxes out at 10-12" and hes about 8" now and finally one convict hes the smallest about 4" I plan on using a 200gal minimum (bigger if I can get the wifes permission) to house the 2 bass, oscar, the bicher and the spotted gar then I would leave the 60 for the other two and maybe get the convict a mate to make food whenever I feel like feeding live. will this work also what filtration do I need for a 200g tank? sorry I know its a lot of reading but your info is greatly appreciated 
Make sure to use good biomedia, about 2/3 of the canister volume. This filter is a powerhouse!
