Should UGF be used for goldfishes?

Please advice the reasons

It can be used for any fish type. I would though run other filtration with it.

If I had my choice of filters, I would choose a fluidized bed filter. The sand particles get pushed up into the water column by the power head on the bottom of the filter, making them float. This means that the nitrosomonas and nitrospira bacteria that convert ammonia to nitrite and nitrate, these bacteria have lots of surface area to live on. It's much higher surface area than a waterfall filter. Fluidized bed filters aren't expensive, either. Link: http://www.aquariumguys.com/fluidizedbe ... a_7cRL0077

The issue with goldfish is they don't have stomachs, so they have to eat very frequently. They aren't very efficient eaters at all, and they make a lot of waste. It's not a bad idea to have twice the recommended filtration (example: using a 55 gallon filter for a 25 gallon goldfish tank) to help clean up all the extra waste. The filter I linked you to above is rated for aquariums up to 300 gallons. It can definitely handle the waste load of your goldfish. :)

Here, I found a video of how a fluidized bed reactor works. At first the sand is sitting there like normal sand, all compressed so the only surface touching the air is the top of the sand. Then you pump air or water (water in aquariums) through the sand faster and faster, which makes the sand bubble more and more, until eventually the sand becomes a fluid. At that point each grain of sand has lots of its sides in contact with the fluid pushing through it, and the surface area is really high. The beneficial bacteria colonize these surfaces of the sand, and so you get a bacteria load per square inch higher than any sponge can produce. They're great filters.

Here's a video of what that looks like as a fish filter: http://www.youtube.com/watch?v=xutRnqYtPdw
See the sand moving around?
