Lighting for sps


New member
I have my sps up top running 4x54 watt ati bulbs. Its a aquatic life fixture with individual reflectors on a 75
2 blue plus
1 purple
1 coral

I have easy sps corals, montis millis birds nests. I would like to upgrade my lighting because i dont seem to have much growth

What would be my best bet
Add more t5s maybe fit 2 more if there is room
Get a metal halide( if so whats a good one)
Or go led? Was thinking 2 vegas or sols. Most likely sol due to the price

I was leaning towards led since i wouldnt have to replace bulbs and electroc bill. Also the dimming effect for morning dusk
