So far I have 4 x 80 watt t5 and 1 x 160w DE halide. What should I add …more metal halide or maybe kessil A500x. I don’t want radions. I want this to be a sps reef overall

i ran MH/VHO for close to 30 yrs with excellent results just a lot of heat and electricity spent, after selling out and taking a 'few' yrs off from the hobby i returned and went with LED only, i really like the energy efficiency and lack of heat from LEDs and they provide great growth and coloration but they aren't up to what i got with MH lighting, so if heat isn't an issue and you can live with the power bill, add a few more MH.
