Hydra 32 t5 Hybrid settings

My 180 gallon 6x2x2 system is in its cycling stage. I am starting to think about my lighting schedule a little harder. I have the 60" Hybrid fixture with 3 Hydra 32HD's. On my last system I ran two of the 32 HD's with an AB+ schedule and had the plastic lens burn out on the V and UV channels(was only at 80% on those channels). No biggie as AI sent me new sets. This has me thinking of maybe changing the LED schedule on my new setup. I plan on keeping mostly SPS up top with LPS and clams on bottom levels. I will be renting a PAR meter once it is closer to turning on the lights.I already have two blue +, One atanic blue and one coral + bulbs installed. Should I keep the AB+ on the LED's and change out the lens every so often or switch it up a bit?

Can you reduce the power on the UV and violet channels? Is the UV true UV (i.e. below 400nm wave length)?
