Alot of the BB tanks are amazing.. especially the ones just show that used the space to perfection... I mean I have only 20LB of sand in my 120gallons - I know the benefits of running a BB its very easy to keep nutrients low to the point your algae will just disappear instantly. And yes after few years it will cause problems but with the cost of this hobby spending $60 every few years to replenish the sand is important. I feel it depends on your system and what you plan on keeping and how much time you want to dedicate to your maintence schedule. If your not going to stir your sandbed and vacumm periodically than go BB. If your going with a minimalist approach then go with sand for esthetics. Never follow recommendation on sand coverage - when in doubt stay in the middle like me.. I am adding 40lb of live reeflakes to give me .5" coverage... Let the debate continue
