Undergravel Filter

I was told that UGF were old technology and bad for freshwater, however I found a few articles saying they were great for saltwater tanks...

Is this true? Or is a HOB still better... also would a powerhead still be needed if the UGF is ok?

For many saltwater fish tank setups an aquarium undergravel filter is the best choice. AquariumGuys recommends undergravel filters for use in saltwater, fish-only aquariums. Be sure to properly maintain your aquarium undergravel filter to prevent damage to your saltwater environment.

UGF was a fantastic choice, oh, back in the 1980s or earlier. The hobby/science has progressed far since then.

No one uses UGF anymore, it has way too many problems. The best filter in SW is lots of live rock + skimmer + a refugium with macro algae. The next best is live rock + skimmer, followed by live rock.

Thats what I thought. I was recently told by a guy who breeds cichlids that it was wrong and that UGF was the absolute best filter. He said it was superior to HOB and canister....

It caught me off guard completely... He runs a business setting up tanks for local businesses and sells bred cichlids to a lot of pet stores around the area.

UGF are very out-dated. The best choice is a LS bed, 1.5-2lbs per gal of LR and aggressive skimming. HOB/canisters/wet-drys will provide a place for mechanical filtration and chemical filtration if desired.

If you went with an undergravel filter would you still need a powerhead to create current? Would the Sand go over the UGF and then the LR on top of that?

This is just curiousity really because I have not yet decided I am going to switch over my 56 gallon. I may just buy a 125 gallon and start new with the whole SW tank.

yes, an UGF is just another filtration method... one that is currently less popular then it has been in the past...

How does one go about setting up a LR filtration? What is required, besides the obvious LR, sand and skimmer?

It is as simple as putting cured LR in the tank. 1.5-2lbs/gal.

That is a bout it. Add a couple of powerheads for circulation.
