T5 bulb choice help

[Stones]

I'd recommend 2 ATI Blue Plus, 1 Aquablue Special, and 1 KZ fiji purple.

If you don't have access to ATI bulbs, 2 Aquascience 22K and 1 Aquascience 15K would work in place of the ATI bulbs.

I haven't used the new superblues from KZ yet, but you could go with all KZ bulbs too by using 2 KZ 14K new gen coral lights, 1 KZ fiji purple, and 1 KZ superblue.

All these bulb combos should result in a ~14 K colour temp which should give your tank and corals a nice colour with a decent amount of PAR.
