CO2 and light

[Aquaboy]

The light for my 29gal planted tank has 2 65watt (6700) bulbs. This provides 130watts. How much CO2 would I need in correspondace with my light? What CO2 system is best? Can I use Flourish Excel as a source of CO2? (This is coming w/ the lights)

With that much wattage you'll definitely want CO2, not Excel, otherwise you'll be growing algae instead of plants. A good target level of CO2 is 25-30 ppm. This is most easily achieved with pressurized CO2 injection. JBJ and Milwaukee both make excellent CO2 systems and you can find them at one of our sponsor's sites. I got a great deal on mine at www.aquatic-store.com.

Btw, what 65W bulb are you using?

The description for the light says that it has 2 switches, 1 for each light. If that's the case, then I will use one of the bulbs at a time. I'll check out aquatic-store.com and see if i see any descent prices.
