I have a 35 gallon Hexagon tank with a Kessil A150W. I am "old school" and usually go by watts per gallon (don't hurt me) and do not know much about LED bulbs, but does the tank have enough PAR to need CO2 injection? Algae is starting to grow. The light distance ranges from 18" to 27", plus I have floaters that are 7" away.

I think you're right. I am gonna order a 3 way regulator from GLA(http://greenleafaquariums.com/co2-regulators/gla-co2-regulator.html) and I think I'll hook up to an existing CO2 bottle. I did some research and found these PAR readings on Samamorgan's LED light compendium(http://www.plantedtank.net/forums/showthread.php?t=160396):

56 PAR @ 18"
42 PAR @ 21"
34 PAR @ 24"

It looks like the majority of my plants will be Medium to Medium-High light and the floating plants are obscenely high.
