ATI T5 Coral Plus (39W) Queries

[Zixuan]

Hello reefers!

My tank's a 2ftx1ftx1.5ft -> LxWxH (PS the photo's old).

I currently a Zetlight QMaven 6600T for my mixed reef and it's doing decently okay. I got my hands on 2x Coral Plus T5 bulbs (39W) and wanted to try it out with my LEDs to see how it goes. But I'm concerned with it browning out the LPSs I have Are there any thing I should take note of? Or of there's a lighting schedule to follow? I had intended the following: 

1. Running 1x T5 Coral Plus first, then ramping up to 2 if it suits (provided pest algae doesn't grow). 
2. Turning the lights on for a 4 hour period everyday. 

However, the question then boils down to this ... Should I run the T5 together with my daylight setting on the zetlight? or should I run the T5s in the evening, when I have a high percentage of blues in the tank?

Any advise is news to my amateur ears Cheers and TIA!

coral turning brown is not due to light alone, it could be due to your nutrient level ( N03 and P04) , what is your N03 and P04 level now ?

Hello! My NO3's at 10 as per last reading, and PO4 at 0.153ppm from my hanna, so I doubt so. I started running the T5s but don't see much difference, maybe its only been 1 week of running haha, but I'll let it run its course and update asap! So far no browning, but a tad bit bleaching... my guess is stress due to light changes, but my torches are bouncing back!
