I know that UGFs are the old fashioned filter systems and people here advise against them. 8O I just wanted to understand better why. I have a UGF
running on a 30 gallon (with HOB
) and I'm going to revamp the entire tank. Is it really a good idea to just ditch the UGF
1. Nitrates. People call UGFs nitrate factories. How do they produce more nitrates than other filtration? (links?)
2. Nitrifing bacteria. I was told that UGFs provide great nitrification because it uses the entire gravel bed to house bacteria -- superior to what any HOB
could provide. For tanks w/o UGF
, are there fewer places the house nitrifying bacteria?
. I have a whisper 20-40 gallon power filter. Will this alone provide adequate or better filtration than a UGF
