It depends on the size of each grain. Fine sand or coarse sand. Also, tye deeper the sand bed, the possibility of having oxygen deprived areas are higher. Anaerobic pockets are areas in the sand bed that do not have any oxygen. Bacteria living there can release hydrogen sulfide, a gas that you do not want as it is toxic to aquatic life. To aerate the sand, you can try MTS - Malayasia trumpet snails which burrows in the sand, allowing oxygenated water to flow in there. Maybe try 1mm coarse sand?

Chiming in here.

I was thinking about using petco black sand (cause it's all that's available to me locally) to cap my MTS (maybe about an inch). But concerned with the MTS going too anaerobic. Let me know what you find out...

If it's dense, good quality, quartz-based silica pool filter sand, and it's only @ 2" depth, the risk of developing any problem anaerobic pockets is extremely low, if not nil, - I wouldn't worry about it.
I've been using PFS for several years in my planted discus tank, and have never had any type of problem with it - it's a good substrate to use.
Even with play sand, at that depth, even though it compacts more, it should not be any problem.

To all on here at this point, except Discus Paul

Please read through this sub forum. There a lot of good threads on this topic that offer accurate advice based in experience. There is no need to fear Anaerobic Apocolypse when sensible steps are taken and tanks are maintained properly. Focus on the tank as a whole vs. the parts and you will be more sucessful.
