CO2 for 90 Gallon Planted Tank

[fishrex]

What CO2 system do you recommend for a 90 Gallon Planted Tank?

 

[Rivercats]

I have a 220g and use this regulator... New Premium Aquatek CO2 Regulator with Integrated Cool Touch Solenoid | eBay.

I use a two way splitter so I can diffuse the CO2 at both ends of my very large tank.... Aquatek Splitpro CO2 Splitter for Solenoid Regulator 2 Way | eBay.

Then this bubble counter... New Aqautek Bubble Counter with Integrated Check Valve | eBay

The I use two of the 1200 Pro powerheads to diffuse the CO2... Aquarium Water Pumps & Water Movement: Marineland Maxi-Jet PRO.
