if im honest, when i googled flora tank, this is what i found
Nice upgrade btw. transplanting an established filter is a quick way to establish the tank however there is some time for it to adapt so mind the ammonia and nitrates anyway if you have shrimp or livestock.
If you are familiar using sand, this fluval stratum should be on par with what your used to. i would continue with tablets to supplement the plant nutrients.
You seem to have your head around planning for this new tank which is definitely a great start. Keen to see your journal soon.
