You will also want to buy the dry ferts I was talking about. Since you are running a high tech tank with high light, you are going to need to dose NPK (nitrates, phosphates, and potassium) into the water column. Read the following thread as it has some very useful information about dosing regimes:

I dose macros 3 days a week, micros the opposite 3 days from macros, and one day of rest (no ferts) the day before I do a %50 water change. This whole process is centered around the Estimative Index (EI) method.

Here are the links to where you can buy the ferts:

Personally, I would buy:

2lbs of Potassium Nitrate (KNO3) for N
2lbs of Potassium Sulfate (K2SO4) for K
1lb of Mono Potassium Phosphate (KH2PO4) for dosing P
ok.. I ordered the ones that you recommended.. not to sound stupid.. ok too late! but which ones of those are micros and macros?
