then if you fill up your tank with LR there really isnt much room for filling up your tank with "fishies"...
LR is a staple of any successful marine aquarium...when was the last time you saw a tank without any biofiltration...other than a QT... a tank needs a place for bacteria to grow (LR LS) to provide biofiltration and the revers is true as well... LR LS provide a place for benificial bacteria and algae to grow...
if there are 2 things that an aquarium needs it is water quality and LR...substrate is debatable...
Sorry, gotta disagree with you RU.
The whole point of LR is that it provides some surface area for bacteria to colonize. So that means that anything with a surface can be used the same way as LR, but very few things provide as much surface area per pound than LR (natural stuff at least).
One such tank where you don't need LR is a seagrass/macro algae tank. the algaes, and plants provid ethe surface area themselves.
I hope my post isn't confusing. I have been up all night. Maybe I can explain better later.
