Beginner planted tank question

[Wulfonce]

My first planted tank is finally in the works. Its a 90g that'll have plants from Long Point Bay, Lake Erie. Fish will consist of Pumpkinseed or sunfish. Right now im sitting at 120 watts of lighting or 1.333* wpg and a 3.5" sand substrate. I read over WyldFya's "Planted Aquariums for Beginners" and need some clarification on a few things.


Fertilization:

I figured on planting the roots in clay pots and burying the pots just under the sand substrate. Can I fill the pots with household potting soil?


Biological reaction (c02):

I think I'll go with the yeast and sugar method in a small container. Would something like a film canister with a few pin holes in the lid be ok, or should I be thinking way bigger? How long would the yeast continue producing c02? Is water temperature a factor in this method? It's a cold water tank.


CO2 Reactor/Diffuser:

So basically I need to keep the c02 bubbles in the water as long as possible. If I construct some kind of "ladder" out of Plexiglas somewhat resembling one of those little kids marble runs and have the c02 source (yeast and sugar in a film canister or something bigger) at the bottom, that's all I need? Surly im missing something here. It seems to simple.

Thanks in advance for your help.

some people do do this. make sure you have a good 2-3 inch sand cap on top. also make sure no chemicals are used. you also might need more light. since i dont know about plants from there i am unsure.

most people use a 2liter bottle. on a 90 gallon diy would be almost pointless. diy tends to last a week or two. the diy co2 is set up out side the tank.

intake of a canister power head glass diffuser reactor are all great ways to diffuse the co2.
