I don't understand why you want to remove your UGF? Just because someone on this forum said that they "suck"? Why don't you try doing some research on UGF and see what you come up with. There are many people on this board, myself included, that use undergravel filters with much success. I actually prefer a UGF to a power filter or canister filter. And if you do end up decided to remove it you need remove the WHOLE thing, leaving the plates under the gravel will cause big problems in the long run.
