Zoanthids Bleaching

Currently using a Dual 39W T5 fixture over a 2oL and I'm having problems with some zoas losing color even though they're on the sand.What could it be?

what bulbs and fixture are you using ? Also your water parameters , flow and liverock / substrate , and filtration and add ons

The system is a 20L lit with the stock Aruba Sun Atinic and an ATI Coral+ bulbs .For filtration I have about 20lb of CaribSea Hawaiian Black sand, 15lbs of BRS dry rock and for flow I have a Jeboa PP-4 working in synergy with an Aquaclear loaded with Seachem Matrix. As of last week the dKH is 7.5 Calcium 410-420 Mg 1200 NO3 0ppm P04 0ppm all tested were with Salifert test kits.The livestock list includes 3 PJ cardinals,2 green chromis,pygmy angel(he doesn't nip on any coral),Raniford Goby,scooter blenny,lettuce nudibranch,arrow crab,10 red leg hermits and 6 assorted snails. @NanoDJS

I had been dosing KNO3 manually for a couple days, but I've been slacking lol,something I've noticed is that even though I raised it to 2ppm in one day it was back to .1ppm within 5-6hrs I think it might be because of all the xenia I have(this was originally meant to be a xenia dominate tank).

Its low but its def not Zeros. The Xenia tell a different tale.

It is possible its an acclimation problem, its actually a pretty good amount of light you have in there. Its also possible they dont like that many xenia in the tank.
