my tank is 120 gallon 48x24x24,
I have 2x54 watt 10,000k and 2x54 watt actinic t5`s with separate reflectors.
Is this enough light if I want to add some corals?
no because if u think about it t-5s are more front end cost but if u get mh than the bulbs need to be replaces every 8-10 months and each cost 80-120$, and its alot more than t-5s on ur energy bill,
