Hur hur.... depends on which theory you subscribe to. Some put zero in main tank with DSB in sump. Others believe the more the merrier. This is probably one of those questions which has 'no best answer'.

Depth of sand bed.

if u are just using it for removal of nitrite and ammonia, u dun need a deep seabed but a vast one.

one which covers a huge surface area.

but if u need it to remove nitrate..u will need to build a deep one.

if urs is 3 to 4 feeet, u need to build one at least of 7 inches deep with grade 0 sand.

that will allow the air to escape due to the depth of the sandbed.

and with proper circulation cos u dun wan the sandbed to crush.

other than that, it's just that straightforward.

good luck.
