Just my personal experience
I had a 6x54w aquatic life t5 system on my 120g. Changed the bulbs for ATI and never really liked it for my corals. Was never happy with it, switched to led lighting and am finally happy. If I had o do it over again, I would switch to an ATI fixture, before going to LEDs
If you haven't bought the fixture, skip it and just go with an ATI , or a tek, but i would skip aquatic life. Just my honest opinion
