I had a 3" sand bed in my old tank.. i have algae problems because i wasnt getting all the deitris... my new tank is BB.. heres the difference with both. I personally think sand is for asthetics unless over 4".... Why go barebottom?
Heres the difference "TIME"
Its faster to do a water change and clean with a BB water change will probably take 5 mins to get all the deitris from the and tank floor if there is any.
With sand its a crap shoot of 20 mins or more depending on much is in the sand floor and also being careful not to distrub the sand.
Personally i dont think theres a benfit to any other than looks and maybe Bacteria growth.
