Do I have adequate filtration?

[addreal]

I have 4 baby tiger Os in my 100g tank. I was just wondering about which canister filter would be the best. I've been looking at the marineland Cseries. Just wanted to know if they are worth all that money.

Get an Fx5 or two and a bigger tank instead of the C-series

bigger tank and a sump is the way to go with 4 messy fish like oscars. id say 180-240

what is the plan for the O's?if your gonna keep just 2 100gal should be ok,as far as filtration I've heard good things about the c360 and 530 models.the 360 +an ac110 might do the trick or the 530 by itself might be enough.I'd go the 2 filter route
