If your getting Fluvals CO2 kit you might as well go buy a 2000 gallon tank. You are going to be broke after words because those little canisters are ridiculous in cost and need to be replaced almost every week.
Go on Amazon and search UP Aqua co2 regulator, Aquatek paintball CO2 adapter, a 20 oz co2 paintball tank, and I would suggest the Aquatek small diffuser, it has a built in bubble counter and check valve. You really need a check valve and bubble counter, or you can ruin your stuff. All that comes to about $70, but you will save much more money in the long run. Make sure you find a place that fills CO2 tanks, it won't be expensive, trust me and it lasts longer.
With CO2 and high light you are going to need ferts. I would suggest dry, but that might not be as easy. So Seachems ferts work as well. You will definitely need Potassium, Nitrogen, Phosphorus, and Iron. Flourish is also recommended for trace elements. That would take care of macros, and micros.
Also make sure the CO2 is turned off when the lights are.
