Maxspect Razor Users, I need some help

[menglish]

I need some help.
I am building a 180G [72 x 24 x 24] mix reef tank and will use 3 16K Maxspect razor. I had two on my my 90G and my LPS did well. I only had a few SPS and they did not do well. The lights reached max intensity for 4 hrs at 65-70%.
In the new 180G tank, i would like to have a bit more SPS corals and have been thinking about adding two 60 inch T5 bulbs, one in the front and the other behind the razors. All this under a canopy.
Questions for you:
1: Is this necessary/will it make a difference?
2:Who has done this or similar additions and what lighting program are you using?
3. What color bulbs should i be considering?

Much thanks.

T5s I've heard have a better affect on LPS. To keep my SPS alive and colourful I run my razors at about 80%, LPS corals hate this so I make shady areas to place them in. In the 180, how far will your SPS be from the lights, mine are about a foot away from mine.

I have not done the aqua scaping as yet, but i i reckon they will be toward the top, about a foot. Lights will be about 6-8 inches above the water

I keep mine at max intensity for 7 hours a day at CH1 65% Ch2 90%. Possibly you may have been light starving your sps. Mine are doing great and are between 12"-18" below the fixture that is on the factory legs. My lps are low near the bottom of an 18" tank (so about 20"-25" away) and my zoas are placed about 18"-22" from the light and love it.

I have a single razor over my 40b at work and all my sps are growing like crazy. I have them ramp up to 100 on both channels for about an hour right in the middle of the day.

when i used the razor on my 50 cube .. i left the lights on for about

Blue channel : 100% for 12 hours with one hour ramping on each side ( so blues stayed at 100% for 10 hours)
White channel : 80% for 6 hours with one hour ramping on each side ( so whites stayed at 80% for 4 hours)

whatever sps i had at that time colored up beautifully .. and my lps didnt mind the 100% on blues

Thanks guys,
So, do you think the T5s are necessary?

Nessesary no. Would they help benefit, sure. I've been happy running straight led for the past year with imo decent growth and color.
