This is probably a worn out topic, but I would like to hear what others are doing.

For my new tank setup many folks have recommended that I don't need a Wet/Dry trickle filter full of Bio-Balls, and that the Live Rock will provide more than adequate bilogical filtration. I don't disagree with this statement ... however, some of the same folks say my current 125g tank is doing great and I shouldn't change anything, which I assume includes my current Wet/Dry trickle flter! :?

I like having the mechanical filter (sheets of blue stuff from LFS) above the Wet/Dry, and change it on a VERY rugular basis so it doesn't supply an abundant source of ammonia/NO2/NO3. And I expect the bio-balls do help keep the oxygen level up.

Can anyone contrast their experience with a system with and without a Wet/Dry filter? I just can't seem to let go of something that has worked so well for me for many years of fresh & now Saltwater aquariums!
