I have heard both good and bad things about undergravel filters, that they clean all the beneficial bacteria from under the gravel, but also that their quite good and some people swear by them. I have a standard filter, it does a great job, but I've been eyeing up the under gravel filters for a little while, just don't want to spend any money before I asked the experts here.
