I need some direction on what I need to have to have a planted 300 gal tank. From reactors to diffusers - too many micro bubbles... how to deliver... I know I need a regulator - 20lb tank - do I get PH controller????

I do not have a sump. I have two canister FX6 filters. Do I need a sump?? It is a fairy older tank.
Could someone show me their setup so I can understand how this works? It is my understanding that 300 gallons is a different ballgame when dosing CO2. Is that true? I appreciate anyone's help and knowledge.
