need advice on pale corals

[Amadod2]

For fish: 1-tomato clown, 1-bi color blend, 1- yellow wrasse, 1-poters angel, 1- sandsifting gobi

For bulbs: 4-ati blue + (3 of them just replaced), 1-ati purple plus that's 9months old, 1-ati coral + also 9 months old. Lights are on from 3pm-10pm, with 1hr start up and shut down with just 2 bulbs

For a skimmer I have a swc 180

I will try and get pics later today
