Wow that's crazy I hope my tank thrives half that well, what are the general guideline on planted tanks when nutrients and plant tabs aren't enough anymore and you need co2? I'm willing to make my own or buy one if needed I'm just curious. Say I get about 8 small/med sized plants in my 29g when will I need to have that extra co2? if ever?
Also should I be testing GH and KH before I pick my plants? I don't have the test for them never needed them before. Also the LFS around here don't have them, online I see API has a GH and KH tester.

I personally use turface as my substrate (its cheap and decent stuff) or you can use a plant substrate
All the plants I have are doing great on root tabs, flourish excel (I use metricide 14 b/c its cheaper in bulk), and a little dry fert mix
I don't think you need to test that stuff if you are on public water. If on a well you may want to.
As for CO2 it will just help the plants, most don't need it, just like it

Ah okay, I'm rockin 2 and half inches of Tahitian black sand; I read that over time the substrate becomes inert anyway so you may as well use whatever you want and add ferts etc.
