I was going to return the T5's that I bought before I set them up and get the T5 HO,
So you do or don't have T5 HO? or just the T5?
The T8 would be around 30 PAR with no reflector and for 2 Coralife Normal output T5 Looks like 22 PAR. Not sure if thats comparable to yours or not. I think you may add them together to get 52 PAR which is medium-High? I'm thinking. Although, I could be wrong I'm fairly new to PAR values too and not to experienced with mixing various types of lights. Co2 may be required. Although since they are different light strips you can always set some lights on then off and times when all lights are on for a burst.
