I think Dwarf clover = Marselia (now choose minuta or quadrifolia or other M. species)
I think Hemianthus got left off... HC for high light applications, HM OK w/ lower light setups - will require frequent trimming though.
Well for my ten, its 3WPG, and i dose with Seachem setup and 5% water change, which im thinking of upping to 20%. Also running Co2 with a 30G filter.
For my 100 thats not setup, and Im carfully setting up, it will be on Co2, dry ferts and im looking for high lighting [still researching.]
I will look into all of your ideas and see what I like best...
if you want to prevent buildup of excess nutrients i would up it to 20-40% wc weekly. 5% as according to Seachem dosing chart isnt enough.
For the 100 i hope you will be going with pressurized co2. Since many foreground plants may go into shock and melt/die if they go from a small tank with good light/co2/ferts to a large tank which lacks some key element. Try your best to mimic similar conditions.
