My 2 cents worth: -
a) do i need some soil in tthe substrate? what do u recommend?
If you intend to do planting then I suppose you need a proper substrate. I would go for soil but I impulsively bought gravel and base ferts as substrate which is not of my preference now.
b) to i mix soil with gravel in top?
I guess you can just pour soil over the top of your gravel. Better check with experience bros here first.
c) any recommendation for soil?
Depends on budget, I would go for 1st ADA 2nd BorneoWild soil (not out yet)
d) any bright ideas how to put soil in a filled tank or do i have to drain all and restart?
You probably got to lower the water level close to the gravel before pouring soil in.
e) thinking of getting seachem flourish excel -- where to get them? I have gone to numerous shops -- none carries it ... not in the east Singapore
I only know of Seaview since it is 1 of the only 2 shops I visit regularly.
f) Is seachem flourish excel a good idea - or u have other recommendation
I would prefer pressurized CO2 method, less hassle for me.
