There are many threads suggesting a depth of 300 mm (12 inches, for those who still use gallons) for a deep sand bed.
Is there any gain in increasing the depth?
We could go as deep as 2 meters in a system being planned by Peterb.
This would be in a 10000 liter drum as an add on to his existing filtration.
Any one?
