it seems most people really dont like the ugf's ...what reasons if you could tell me what is so bad about this kind of filter that i should not get one of these?
There is a contingency of people who don't seperate filter failure from lack of maintenance very well. UGF's are one of the most neglected, and poorly maintained filter formats out there and therefore they have developed a bad reputation. Secondly, UGF's are primarily a bio filter, which leaves something to be desired for mechanical filtration.
Most people who use UGF put them under their gravel, and never do anything to maintain them, then when they casue problems, they write the filter off as bad. I would gladly stack my ugf against any other filter format in a maintenance free time trial. The fact is that any filter if not maintained, will eventually cause problems, and the UGF will be the last to go. For more information read this article:

I run UGF's in reverse flow configuration on all of my tanks, and probably always will, there is simply no comparison when you add cost, ease of maintenance, and bio-filtration capabilities. There are other filter formats capable of the same things, but none as inexpensive, dependable or easy to maintain IMO. I much prefer the Reverse flow set-up simply because it has the added bonus of mechanical filtration, and eliminates any need for vaccuming gravel. I have run UGF's in conventional configuration for long periods as well and there is a little more maintenance involved, but they are still very easy to maintain.
I also firmly believe in using multiple filters and multiple formats to accomplish multiple things in my tanks. IMO there is no "one size fits all one type fits all" answer, but rather many good formats with many different capabilities so that a hobbyist can adjust things to their liking. My recomendation is find out what people like about each format, figure out what you want to try and go with it. if you don't lke it try something alse and Yard sale the leftovers. You will find what you like, and what works best for you. Don't be afraid to customise either.
