If your goal is to go strictly biological, does the size of the tank matter in relation to the depth of the sand bed? I mean, just because it is a smaller tank, does not mean there should be less sand per gallon, right? 4" of sand in a 75 gal
, is a lot more sand than 4" of sand in a 55 gal
but relatively speaking, they should provide an equivilent amount of biological filtration per gallon. If I am missing something, please let me know, as I will be adding sand this week (75 gal
with 3-4" DSB
Or, do you just mean that 2" is enough given his large amount of rock?
