I’d set up tank something like this,
Plant substrate plants
Fill - run filter for awhile to test for current release of new plants (note do not run your High Flow device for a couple weeks or until you see good root development, low thorough flow is what plants like)
90% water change (to remove all the whatnot released on the planting - from plant media and substrate)
Refill to a comfortable working depth - so I’m not worried about spraying the substrate plants (all tissue culture I believe you said - where are they from? You can pm )- then place the epiphytes
Carefully finish filling tank - if you accidentally cloud from hitting the substrate etc, just do a running water change (like Filipe Oliveira video)
At this point, everything should be planted and water pretty much same as tap water parameters
I’d not bother with Stability until you add fish (that’s Seachem’s Stability method)
Then water change 50 - 80% every day, or other day, or at least every third day - you can choose depending on work schedule and plant inspections (a Python Clean type system makes this very easy, George Farmer shows using intermediate bins and pumps)
If you see any melt, then water change
Make sure that Buces get decent flow so no debris settles (seller should have particular advice to limit melt on those costly Buce and Anubias)
Frequent large water changes mean tank water should remain fairly stable
Daily fertilizers in small - as usual, I’ve forgotten what fertilizers you’re planning
Light - it’s a relatively tall tank so I’m not worried about “excess” light (as Kessil 160 not 360)
I’d run the Kessils at 80-100% (I do like to ramp - maybe 30 min - depends on ambient light) for 5-6 h/day
If tank receives significant ambient light, I’ll run CO2 24/7 - low bubble rate outside photoperiod, higher during photoperiod
