I am realitivley new to saltwater, but what really matters is weather you want a
DSB I belive a
DSB is 4 or 5 inches deep. With the rock it depends on weather you have
LR or base rock, but with rocks and sand there is no proportion thing. Its really up to you. Some people have a wall of rock with hardly any sand which would be called a
BB-Bare Bottom tank, while yet others will have a
DSB-Deep Sand Bed, and yet other may elect to have both. Again the choice remains up to you. Having a lot of rock and a lot of sand depends on how much filtration you want. There is always a lot of debate over weather a
DSB is a problem or a nuisence. If you check out all of the podcast there info on all that I mentioned here. Sorry if I confused you, again I am not an expert by any means and will most likely be debunked
lol.
