I've been very curious about bare bottom setups. I understand some of the common pros/cons of bare bottom. Down side seems to be less biological filtration, less ph buffer, and for alot of people it just comes down to the look. On the plus side, less detrius traps, easier to maintain high flow rates to keep everything suspended in the water, easy cleaning, and so on. I'm curious about the more important info, does BB mean you must dose ph buffers, calcium, etc. Any advise or info would be great. Thanks.
