So what's the general consensus on using undergravel filters? Are they
good or bad?


Thanks to all the replies. I'll think when I change over to tropical I'll
take it out, and see how it goes.

Jen,
With the types of filters available these days, and ease of care with
them, don't bother with an UGF.
If they're not maintained properly they become cess pools.
With an external power filter, or even a canister, all you need to do
is rinse out the pad in old tank water and replace it inside the filter
housing. By doing this you don't lose any nitrifying bacteria like you
would if you rinsed it under tap water or simply replaced with a new
one. The only time a new one is needed is when the old one has holes
worn in it.
