Freshwater filtration HELP

[luddy1997]

Large aquariums are new to me and I will soon be ordering a 120 gallon acrylic tank with 2 drilled overflows. What would be my best filtration method? Thinking I would prefer a sump system so I can put heater, UV, etc in this compartment and not in the show tank. Would love to hear all recommendations on equipment, pumps, media, etc. Thanks Jeff

I have several big tanks and 1 has overflows on that 1 I have a wd200 filter with bio balls made for 200 gallon tank my tank is a 180 gallon I also have 2 fluval 405 pumps on it and it runs great. I don't know that I would trust running just bio balls alone doesn't seen to be as good to me as the canister filter. If you go with a sump make sure it has micron bags or similar to help with filtration. My sump has bio balls and it had a thin pad on top where the trickle part of the system is and it would plug up quick and would flow out on the floor so I have since then takin the pad out. And no issues since. So basically if you go with a sump make it have extra pads or filter media the more the better because bio balls alone won't keep it clean an clear.

Thanks for your reply. I am considering this tank.... Fish Tanks Aquariums Custom Made Acrylic Reef Saltwater | eBay and he also offers this sump tank as well.... Sump Fuge Aquarium Tank Saltwarer Fish | eBay. I think this has the space for the micron bags in the first chambers and then I was going to fill the middle (refugium area) with the bio balls and other media. I am researching the pumps now and Fluval seems to be a winner. Why would you need two pumps? Would you recommend a diatomic filter as well for weekly/monthly cleanings? Thanks again
