Just to add on what's already been said:
Banana lilies are coldwater and usually require a period of dormancy in the winter in order to stay at full health/ In some cases they can stay alive for a couple years without a dormancy period, but they will eventually die off.
As far as I'm aware cherry shrimp do not eat detritus, they eat biofilm which grows on plants and driftwood. I don't know of any snails that eat detritus either, however, copepods do break it down faster and are usually a benefit to NPT's if you get them from a sterile colony.
Pretty much everything said is perfect. I like to use worm castings instead of rich soil (Worm casting nutrients are water-soulable, which may not be the case with miracle gro depending on the compost used) and mix it in 50/50 with a poor soil, and mineralize it before use. This shuts down on algae outbreak greatly and also reduces ammonia and nitrate spikes. Another alternative are snail castings (from our aquatic snails) but it takes a long time. Generally it takes me about 3 months and over 1500 ramshorn snails to collect enough snail castings to mineralize, worm castings are cheaper and more readily available.
I would wait at least 2-3 weeks before adding the fish. The initial ammonia spike can be pretty bad, plants absorb out the nitrate and not the ammonia, so the first few weeks are suggested to be run without fish. Test the water after two weeks and if it's all clean you can add the fish, if not, wait until it reads as 0 ammonia, 0 nitrite, and 0-15 ppm nitrate.
