I'm using fine Monterrey sand, which is akin to shredding money for a
substrate by the time you pay the shipping.  Anyway, I haven't had a problem
with tight packing because of MTS, which I know have been mentioned today.
Haven't had any plant root or hydrogen sulfide issues in the sand.  I might
mention that I have a lot of escargot shells in that tank for brevis, and I
have had H2S issues with unoccupied shells.  Every so often I pull them out,
empty them and put them back.  I'd never heard of that until it happened to
me. Killed some F0 cichlids that weren't cheap.
