True, but poo will also be trapped by the gravel which is where the majority of excreted nitrogen is going to be.
Sand is still much easier, but gravel has some potential
Agreed!

Thanks. I didn't quite understand the last question but to calculate amount of substrate to use go to: Substrate Calculator
I'm almost positive there's.nothing that's backed with evidence or actual research on the topic. The thing to keep in mind about deep sand beds is that they are only going to be good for a few ppm of nitrate a week.I just got up so if this doesn't make sense I'll try again later!
No that's a basic calculator. I use the rough guess method in FW, add, add, store. Half a bag of subs gets used up eventually.
I think mebbid may have answered this question.
(Generally sumps are not big enough)
What is big enough?
(How do you calculate the size a DSB needs to be to effectively condition 100 litres. Normal stocking)
It isn't built yet! So it can be any size, is there a way to work out a minimum effective size? Like in reef environments they recommend X kilo per litre for rock, I wonder if there is a sand bed size equation maybe based on footprint size instead of water volume.
A tank size X needs an isolated DSB bed size of Y to have an effect on nitrate reduction. There are some cases where an in tank DSB is not recommended, digging species etc.
